How does cross-play get redeemed?

My friend and I split a copy of this game. He wanted to play the PS3 and gave me the code to use on my Vita.

I'm looking at this now, and I don't want to redeem this code he gave me because I believe this is the online pass. I don't want to enter this code in because I don't want to screw him out of his online pass. If I redeem this, I DON'T get the Vita version, right? And can another online pass be purchsed with a PS Network card?
