I thought it was on purpose gameplay-wise, and I personally like it this way, because it gives you a few more strategies to play with.
Example: How to store 70 units for as cheap as possible?
In one single province it would take 3 gold, however, if you split it between two provinces (35+35), it's just 2 gold
just a little tweak that kind of supports the "easy to learn, hard to master" phenomenon
