I'm not saying its fake, but let's just say I have a ton of these. Have followed these cards on ebay for a couple of years and have never seen anything other than a single color jersey on any of these cards. The only multi color jerseys or patches that I have seen that are of finals jerseys have been the 06-07 Topps Big Game /50 patches and auto, and the /25 00-01 Topps Chrome versions.
You can see it here, you can see a topps chrome patch here. One more note, the shaq patch has been offered on ebay on and off for the better part of the last year.
Update: The guy emailed me and says that he pulled the card out of a pack. Meh. I'm skeptical.
