Snipping the 99% of Talisman's post with which she has no argument,
Annemehr notes that Talisman says of Snape: 
> Who else was there to deflect the dementors the first time through?

The time-turned version of Harry was there, ever since 9:00, to 
deflect the dementors.  This is so because later on (12:00 
midnight), Hermione is going to use her time turner on them both.

A neccessary result of time travel to the past is that an action you 
perform now (whatever it is that ennables time travel) is going to 
have an effect in the past, before the action was ever performed.

The reason I believe JKR has written her time travel this way, where 
there is only one version of 9:00 to 12:00, is from reading about 
the time just after 9:00, when the "original" HRH (in invisibility 
cloak, about to leave for Hagrid's) and the "time-turned" HH (hiding 
in the broom cupboard off the entrance hall) each hear the other 
group's footsteps.  So "original" HRH heard "timeturned" HH run 
through the entrance hall the "first" (and only) time through that 
moment.

But you are probably tired of hearing this!

who is always ready to jump into the time-turner fray...
who is aware of the many different types of time travel theories in 
literature, etc....
and who is muleheadedly sure of her interpretation!
