Isso dependeria muito de quem você pergunta. Os escritores acreditam que Cap voltou na mesma linha do tempo e, portanto, haveria dois Caps do ponto de vista deles.
Fandango: So people are asking... Does this mean an old Captain America was hanging out this whole time while another Captain America was saving the day?
Christopher Markus: That is our theory. We are not experts on time travel, but the Ancient One specifically states that when you take an Infinity Stone out of a timeline it creates a new timeline. So Steve going back and just being there would not create a new timeline. So I reject the "Steve is in an alternate reality" theory.
I do believe that there is simply a period in world history from about '48 to now where there are two Steve Rogers. And anyway, for a large chunk of that one of them is frozen in ice. So it's not like they'd be running into each other.

Os diretores, no entanto, afirmam que, quando Cap voltou no tempo, ele foi para uma realidade diferente e, portanto, as coisas teriam acontecido de maneira diferente lá.
At a Q&A event that recently happened in China (via Reddit), Anthony & Joe Russo were asked a series of questions about the biggest surprises and moments in Avengers: Endgame. Thankfully, someone asked about this final scene and whether or not Captain America traveling to the past resulted in a change in the primary timeline. Since he lived a life with Peggy Carter and then spoke to Sam and Bucky in the same timeline that he had just left, how is that possible? One of the Russo brothers answered:
“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.”
So does that mean there are two Captain America’s in that alternate timeline?
“Yes, there were two Captain Americas 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 a 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.”

No último exemplo, não temos evidências do que aconteceu e, portanto, não podemos dizer com certeza se Sharon existe, se ela o faz se eles se beijam ou não, etc. No entanto, no primeiro, sabemos o que aconteceu. mas tecnicamente Sharon não era sua sobrinha quando ele a beijou. Ela era sua futura sobrinha, pois esse cap ainda não havia se casado com Peggy. Lembre-se de que você não pode voltar no tempo e mudar o futuro no MCU.
Smart Hulk: And secondly, time doesn't work that way. Changing the past doesn't change the future.
