Absolutely, it applied to any part of the game. The only difference is that your exact knowledge in the opening may be lost very quickly if say, you have memorized and hold a firm knowledge of the dragon, and your opponent opens 1. a3. You may think this is a bad move, but if they guy playing it knows it well, then this may be his exact knowledge -- especially if he's rated 2400 and you're reated 1200.
By the way, none of these ideas are mine. I'm simply paraphrasing Mark Dvoretsky. Dvoretsky makes it clear that we can not learn enough exact knowledge to win most of our games. He says our time is better spent learning how to think rather than learning to memorize positions. A case in point is a current game of mine. The exact position I know is queen vs rook, but in the real world things just aren't that clear. So we must use our exact knowledge as a guide, not as an exact plan.
The same is true in land development. If we survey the elevations of a field in preparation for precision land leveling we can not accept our cut-sheet as the absolute infallable word of god. It is based in mathematics so many people consider it just that, but it is also based on a sample and not a population. As field work is done the standard error of our estimate becomes less and we must adjust the mean elevation to this new knowledge.
This analogy can be applied to chess. We can not develop a plan that will take us from beginning to end. A good plan may take us only a few moves further into the game. Plans are guidelines that we use based on general principles, experience, and our evaluation of the position. Things change. You may want to keep pawns on both sides of the board because you have a bishop and your opponent has a knight, but if you convert this dynamic piece advantage into a static advantage, say an outside passed pawn, then your whole plan must change.
I'm not sure what you mean by many differnet lines, but if you mean an understanding of every opening then the answer is no. You are much better to learn a single opening as white, a single defense against e4 and a single defense against d4 until you become a master. You can't learn enough about all of the possible defenses against 1. e4; so, don't play it. It would take a lifetime for most of us to learn the Najdorf alone. We sure can't learn all of the variations of the Sicilian, French, Caro-Kann, Philidor, Ruy Lopez, etc. There is nothing wrong with Larsen's Opening, the Polish, English, or Birds. With each of these openings, at least, you can direct the game in your direction. If you play e4 you have no idea wher eit is going. Bobby Fishcer could do it, but most of us are not capable. 1. d4 is a differnet matter. It is more positional, but there again, most of us are not capable of understanding positional play until we reach 2200. To play d4 you have to have a firm understanding of how to coordinate your pieces together. Most great players master e4 before going to d4.
Do any of you watch the television series Numbers? I was really disappointed with Charlie, the mathematics professor on the show, when he identified 1. d4 Nf6 2. c4 as a Sicilian Defense. Of course, another professor quickly said no it couldn't be a Sicilian since black didn't push the c pawn. Finally, Charlies girlfriend played the next few moves 2... e6 3. Nc3 Bb4 and said it was a Nimzo-Indian. I didn't know if they did this because she was from India.
My wife, an RNC, gets upset when they make obvious mistakes on the show House. "You can't shock a baby. We don't do that in NICU," "You can't use an air-bag with the oxygen supply line still in their nose." Why can't these people try to get things straight? Russia with Love, and Casablanca are about the only shows I know where they at least get the moves right. Of course, I did like Pet Detective where the white and black queens were switched as swingers.
