Yeah you did, I was just expanding on it a bit in case someone wants to go back and have specific reference points to look for while watching it.
I love Glenns character, but his death is needed. I firmly believe they have been leading up to it as well. He was the one looking at the pictures of the bashed in heads after their raid on the saviors. He killed his first person in that raid...the entire series, and he finally killed someone. He has always escaped such inescapable situations. Maggie needs to be less attached to the group to move forward. Rick needs to go to crazy town again.
There is also the tree theory.
Behind Negan during the final POV shot, you see trees. This means that from the point of view of the person being killed, the line of sight from him, to negan, and beyond is not facing the RV, but in front of or behind the RV. There are only 2 people with that point of view. Eugene on one side of the half moon of people on their knees, and Glenn on the other. Everyone else would have the RV as the backdrop to their POV death.
