Nice catch. I too think FSA was made as a praquel to LttP, but to answer bbevington90 and Locke's timeline theories, since the Sealing war is, or at least was originally supposed to be OoT's AT events, I'm quite sure the most probable placement for FSA to be like this:
......./--FS/FSA--LttP
OoT
.......\MM--TP
But Ganondorf is out of the Dark Realm in FSA's beginning, right? Wrong. He kidnaps the maidens as soon as the game starts, so he's freed as he also tries to in LttP. Then he's imprisoned back in the DR, but with the FS as an extra seal (much like the MS was in OoT), so the second time is harder for him to get free. Of course this theory is also for who believes FSA to be the origin of the trident, but as I stated in another thread: the trident was truly in OoT...
Oh, yes, consider that I HAVEN'T PLAYED FSA YET. I base my statements on videos and plot descriptions I've seen and read, so I may miss some detail.
Let's get to the point. Is Link the same? I always tought he wasn't, but know that I think of it, there's no reason to do so. We all know she says "My name is Zelda" at the beginning, but it doesn't count, that was probably just a psychic SOS, she would have no reason to specifically call a boy she never met before. When they first meet in person, instead, she doesn't present herself, nor he does, but she seem to already know his name!
This is a very sweet theory I'll start considering from now on. Anyway we can't say anything for sure and I also like the idea of the Knighs of Hyrule being the Four Links very much!
Also we can't base it on the name too much, since Hero of Light doesn't seem to have any particular meaning, such as Hero of legend, it's not related to his particular powers or actions, opposed to the HoT or the HoW.
By the way, is there any fan-given hero titles for them? I'd call them "Hero of Splitness" And "Hero of Bunnies".
Basically light is goodness, opposed to darkness that's evil. So they're both Heros of Light, just because they both fought the Darkness...
