Yeah, maybe and that’s the problem with this plot and why people are spending their time not talking about the story but about the inconsistent mechanics. Everyone seems to have their own way of dealing with this clumsy and frustrating plot by trying to squeeze it into their own personal canon, that’s yours and the other one is mine. I saw this and they seem to kinda address it but of course they don’t want to pre-empt future films.
Spoiler quote.
Q: Peggy Carter was probably already married and in her mid-40s in 1970, in that case, what year was it that Captain America went back to dance with her?
A: We can’t answer it, for now, this is a story that happened in an alternate reality. Maybe it will be revealed in the future.
Q: Did Captain America’s action at the end affect the timeline? Does that mean there was a time where two CA existed in a same universe?
A: To me, Captain America’s action in the end wasn’t the fact he wanted to change anything; it’s more like he has made a choice. He chose to go back to past and lived with the one he loved for the rest of his life. The time travel in this movie created an alternate reality. He lived a completely different life in that world. We don’t know how exactly his life turned out, but I’d like to believe he still helped many others when they were needed in that world. Yes, there were two CA in that reality, it’s just like what Hulk said, what happened in the past has already happened. If you go back to past, you simply created a new reality. The characters in this movie created new timeline when they went back to the past, but it had no effect to the prime universe. What happened in the past 22 movies was still canon.
