I see what you’re trying to say, and it would make perfect sense except that when Hiro first meets F-Hiro, F-Hiro says something about how he hadn’t gone back yet (IIRC). But then later on Suresh recalls Peter telling him about the cheerleader on the train, and Claire is alive, but Sylar still regenerated… GAAAAAH head a’splodes
The only thing I can think of is that at some point off-camera, after we first meet F-Hiro, he goes back and delivers his message to Peter.

When Present-Hiro and Future-Hiro meet in the future, Future-Hiro had just gotten back. This was shown in one of the online comics. Here’s my recreation of the Heroes timestream:
Timeline 1: Sylar kills Claire, gets regen powers. Hiro stabs Sylar just prior to “boom”, but Sylar heals from the wound and goes boom anyway. Presumably, TL1-Hiro has time to get away between stab and boom. This is the Hiro who goes back to warn Peter causing…
Timeline 2 (seen in “5 years later” episode): Cheerleader is saved. Peter goes boom, and survives due to having her healing ability (although the scar is problematic). I see a few options here:
TL2A: Hiro stabbed Sylar, and (for some reason) left the scene. When Peter exploded (and Nathan spread that Sylar was responsible), Hiro assumed that Sylar had gotten to Claire at some point out of his sight and survived the stab. The fact that Bennet has kept Claire hidden makes this plausible, TL2-Hiro may not konw that Claire is alive in his timeline.
TL2B: Prior to the explosion, Sylar kills Candice, giving him the “illusionist” power, and used that to make Peter look like Sylar. Hiro attacks “Sylar”, he heals (since Peter has Claire’s power), and Sylar / Peter goes boom. Sylar continues his brain drain rampage, helped by the fact that everyone thinks he’s dead and he can make people see whatever he wants. Nathan is brain sucked (this could actually be before the explosion), and Sylar takes his place. Masquerading as Nathan, Sylar continues / starts the misinformation that he caused the explosion.
TL2C: Hiro never got to Sylar, since he accidentally time-jumped five years forward after getting the sword from Linderman, and was missing during the whole encounter. Unfortunately, this should mean that Future-Hiro doesn’t exist. And he definitely did live through the years after the explosion, since other people in TL2 know him (Bennet, Peter, Niki, Nathan, etc).
So Present-Hiro-in-the-future time jumps back to “present” with Isaac’s uncompleted last comic, branching the future yet again (Timeline 3), which is what we saw.
One complication with TL2 is that the future Hiro we see is originally from TL1, so may not know the actual events of TL2 (and on preview, this apparently has been hashed out while I was typing). So when he was talking about Sylar regenerating after being stabbed, he was talking about what happened in TL1, not TL2. Maybe Hiro’s memories of the TL2 history merge soon after he returned from warning Peter (or TL1 and TL2 were so close that his friendships / contacts existed in both). It couldn’t have been immediate, since Future-Hiro had to ask Present-Hiro and Ando whether or not Claire had been saved. And Future-Hiro may have had incorrect information just due to not being present at certain times or making wrong conclusions.
Personally, I was liking the sound of TL2B, so was rather surprised last night that Sylar didn’t get to Candice.
