I come back to my own personal theory on time travel analysis; time
only moves forward. The only way to keep yourself from going crazy
trying to resolve time paradoxes is to start in the past and move
forward through time as you document the history of the events.

Starting back in time-

Harry/Ron/Hermione hide in the entrance hall until it is clear and
they can go down to Hagrid's.

Time move forward slightly-
It is a historical fact that Harry2/Hermione2 join the time line
shortly after H1/R1/H1 go down to Hagrid's.

Time move forward-
H1/R1/H1 do their thing while H2/H2 hide and wait.

Time move forward-
The Dementors are closing in around Harry1/Hermione1, a Petronus is
cast from the far side of the lake and it saves H1/H1. History will
tell us at a later time that the Petronus was cast by Harry2.

Time moves forward-
Harry1/Hermione1 are in the hospital room and Dumbledore has them
travel back in time.

Time moves forward slighty-
Harry2/Hermione2 approach Dumbledore outside the hospital door just as
he is about to lock it. When H1/H1 have disappeared, H2/H2 enter the
hospital ward and this series of time travel events are resolved.

Did Harry2 have to conjure the Petronus? 

Let me ask, did Washington HAVE to cross the Delaware? Did Nepoleon
HAVE to go to Waterloo? Did Custer HAVE to go to the Little Big Horn?

No they didn't HAVE to, but they did. Those are historical facts, and
equally so, it is a (fictional) historical fact that Harry2 cast the
Petronus.

He was there to do it because 3 hours ago, he covertly joined the time
line and waited until the moment that the Petronus was cast, then
realized he was the one who cast it, and so he did. He did so, not to
fulfill some pre-ordained destiny, but to live out what he knew to be
documented history. He could have hesitated, he COULD have not done
it, but why would he do that? Once he realized it was he, Harry2, who
cast that charm, why would he not do so again? The alternative would
have been to let himself die (or be kissed). So naturally and
logically, he cast the charm and saved himself. Ignoring fate and
destiny, and viewing it from the point of an intellectual choice, how
could he and why would he choose not to do it?

Time paradoxes only drive you craze if you start in the future and go
back in time. The only sanity saving way to analyse it, is to start in
the past and document time as it unfolds then accept history as history.

Just my opinion.
