Moto X Pure and OS updates

[AC Question]

If I purchase a Moto X Pure, which is factory unlocked for all carriers, how will I receive Android OS updates? Will they come from Motorola or Verizon? Since I will be swapping the SIM from my current phone into the new Moto X, Verizon would not know to send an update to my phone.

These will come from Moto.
