I think PS2 REZ reprint answered that question. IT was rare selling hot, and then magically a fresh batch was printed. So now we have two copies floating around,. However that was like a slap in the face from the publisher. They think "people buy REZ to play it" when people not only play it but collect it.
So if the Switch did the same thing would it matter?

Question? if a game is ported to the Switch and it gets a remake which is on PC, which version matters?

It is like GCN and Beyond Good and Evil or PSO. If Ubisoft and SEGA had focus on the GCN alone would it be a better game and would have been more collectable, because the fact you can still play those games on a Wii. We would have BGAE 4 by now.
