“ Nothing can bring back the dead except the time turner “ meme

Ok I have something to say - people are like they used the time turner to save buckbeak but he was never killed! The part where the executer “killed buckbeak” was him hitting the pumpkin otherwise they would have just have the executer just leave instead of hitting the pumpkin - and while technically you could maybe bring back the dead with the time turner that doesn’t mean they did it was showing how that before they went back in time that while the first time everything the time when they used the time turner had already happened (proof being the rock that was thrown at Harry’s head ) which means buckbeak was already free!

Or am I understanding this wrong...?
