The splits however were prevented. Re-read this quote:

"The Infinity Stones create what you experience as the flow of time. Remove one stone and that flow splits. Now, this may benefit your reality but MY NEW one, not so much. In this new branched reality, without our chief weapon against the forces of darkness, our world will be over run. Millions will suffer. So, tell me, Doctor, can your science prevent all that?" (Understand? A split can only happen if a infinity stone is removed from it's reality but since Steve returned to the exact moment it was taken so they never left.)

"No, but we can erase it. Because once we are done with the stones, we can return each one to it's own time line at the moment it was taken. So, chronologically, in that REALITY, they never left." (So every time they went in a different time they created multiple alternate realities. The Ancient One later said she couldn't risk her new reality on Hulk's promise.)
