time-travel in MCU, just like in Marvel comics, actually creates alternate realities - however the alternate realities were kind of undone by the stones being returned to their original places: time-travel messes things up even when they try and make it paradox-free, because time-travel in itself is a paradox.

time-lines can be changed, they create alternate realities - we've only begun to see that in the MCU, due to the cosmic nature of the future films we'll likely see even more of this weird timey-wimey stuff and all the headaches that go with it.
