The colonies weren't arbitrary subdivisions though, and they weren't created by the sovereign. They grew out of various disparate colonisation efforts over two hundred years.
They had their own cultural and religious character, in many places very different from each other.
It'd be similar to an individual state having a revolution today and assuming most people would be loyal to their local counties, even though they acted in concert to overthrow their state government.
Plenty of places that could be the case. Just as an example, if California seceded for whatever reason, it's entirely conceivable that they would want to split into at least partially independent regions.
It's real sure, I don't see how the worship part is logical.
