The point isn't whether or not SoJ/Smertios believe that quote...the point is you can't use an outdated 1993 box any more than you can use an outdated 1998 director quote. Their both old, unsupported, and obsolete because of all the releases since then.
Ah, but if the releases since then don't obviously and perfectly destroy the quote or the box, then they can still be taken into account. You can't throw it out if it's not obviously disbanded. If I tell you that my favorite color is yellow and ten years later you see me and i seem to be wearing nothing but red, that doesn't mean yellow isn't my favorite color anymore. Yes, it's evidence that it's not my favorite color anymore, but in essence, it doesn't prove anything because it's not 100% evidence.
Yes, the quotes were made a while ago and so was the box, but there is no 100% proof that the quotes are wrong which means you can't throw them away just because they are old.
Certain quotes, like WW being 100 years after OoT, can be ignored because in the game, itself, it says that WW takes place "hundreds" of years after OoT, not 100 years.
The fact that there is no proof that ALTTP doesn't go before LoZ/AoL means that the box saying Link is the predecessor of those Links could still be correct, whether or not it's an old, outdated box.
