Not going to keep reverting because obviously that's unproductive and just causes an edit war that can get us in trouble, but it is explicitly said that this isn't like Back to the Future where you can create branching timelines, the exception being, as the Ancient One says, if the Time Stone is disrupted. Banner explains to her that they are simply keeping everything in one stream of events, and that's what they do. Granted, there's little blips of change in the Time Heist points, but they set everything back onto course in the one timeline. Steve staying in 1970 doesn't create a new reality, it's the way it's always been, because that's what they do - set the timeline back on course in all the Time Heist spots. Since 1970, there have been two Steve Rogerses out there at any given point. From 1970 to 2011, one older with Peggy and one frozen in ice. From 2011 to c. 2013, one older presumably with Peggy and one out of the ice. From c. 2013 to 2016, one older away from Peggy at least in January 2014 and June 2016 for the safety of the timeline (and Peggy has dementia so doesn't remember marrying him), and one with the Avengers. From 2016 to 2023, one older on his own and one enduring everything we've seen. Older Steve knows when to go to Bucky and Sam because he knows when he left.
