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, CA's action in the end wasn't the fact he wanted to change anything, it's more like me 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. https://www.reddit.com/r/marvelstudios/comments/bj0it4/joe_russos_qa_about_the_plot_of_avengers_endgame/
