Where the increment was nested inside the decrement in #3184, swap them.
For cases like this, I think it is more intuitive to put the decrement on the inside. It fits with our physical conservation intuitions: The amounts in the decrement's return value are the amounts extracted from the decremented seat's allocation. That amount in turn is used to increment the allocation of the outer seat.
