Nope. The quote just said Starscream's version of events are a lie. Nothing about the Predacons being alive was said at all. There are two versions of events. Starscream's version where he bravely faced off against them and killed the Predacons with his bare hands which everyone already knew was a lie. And then there's what we see in the flash back where Starscream runs away like a coward, accidently triggers those automated cannon, and the cannons kill the Predacons just out of sheer dumb luck. In both versions of events the Predacons died. Starscream just lied about how they died. Starscream's lie does not in any way shape or form prove them to still be alive. The flash back would have to also be a lie by Starscream in order for them to be alive but that makes no sense. Why would see a different version of events if it was also a lie?
