Since he runs into the kids as soon as he leaves the room for them 
to time-travel, I get the impression that while he is saying this to 
them, TT!they are in the middle of saving Sirius.

Here's my problem: in order for Harry to survive the Dementors, his 
time-travelling self had to be there.  But his time-travelling self 
was only able to be there because he time-travelled.  But he can't 
have time-travelled without being saved... so how does he get the 
opportunity to time travel in the first place?

The consequences of simply saying that time never occurred in a 
different way severely contradict everything that JKR put into the 
mouths of McGonagall and Hermione.
