They don't just jump in time though, they return to the place and moment they were sent (hence why they always go back to the root timeline and not forwards to the 2023 of the new timeline), that's what the test run scene is about. For Steve to jump to 2023, he would have to appear in the tunnel before them. He didn't, so it's the same timeline.

It could be any year soon after 1947, and Peggy and Sousa could easily just break up beforehand. I don't at all expect her to just drop him for Steve. Plus it's interesting that despite everyone's assumptions, the show never gave us a moment of Sousa saying Steve saved him.
