The way I interpret it is all the new timelines would be doomed if the branches existed so when Cap cut them the timelines were saved.

When Cap returns the Time Stone, for example, he would have to return it to the same Ancient One who just gave the Time Stone to Bruce. That erases the branch that did happen (It couldn't be prevented) so Cap saves that reality and others.
