If I had to guess, it's because when the previous upgrade work was started, it wasn't know what further upgrades would be done.
So each area is upgraded to the same planned configuration, to make sure that it can be technically supported in the same way across the network.
Now that the further set of upgrades have been give the go ahead, a new upgrade configuration will be done in each area - so again at the end of the work, each area is the same.
Swapping to a different configuration halfway or three quarters of the way through a project introduces complexity that would increase costs.
