Yes, you'd care about P and not U, because there's a chance you'd end up on P. There's zero chance you'd end up as U.

Why are you saying that? If you don't answer this question, of why you believe there's no chance of ending up as the upload, what's the point of writing a single other word in response?

I see no meaningful difference between first and second example. Tell me what the difference is that makes you believe that there's no chance I'll end up as version U.
