"u've" has got to be the most interesting grammatical construct I've seen online. I mean look at it, it's like he's trying to be correct, but not at the same time.
Hey, that's a subtle observation. I wonder what linguists would call this. It looks a bit like an overcorrection (the classic example of that is when people use "I" as an object, as in Bill Clinton's famous campaign line, "That's very important to Al Gore and I"). But I'm not sure it's the same thing.
