Hey guys, check this out. It's a trope called "Timey Wimey Ball", named in honor of the Tenth Doctor's famous line. It basically describes how due to the many time travel theories out there, different shows adopt different ones. However, sometimes within one show, it will go against the time-travel laws it has already set, which is the case with Doctor Who. That show seems to have utilised every time travel theory in existence from ontological paradox, to alternate timeline, and even butterfly effect. I think it’s the same deal here to an extent.
