That's what I thought too, but one of the designers just wrote in the next thread:
Tip #4: On a replenish action look at the cube, and then decide where to play it. When replenishing a city you can draw the replenish cube first and then decide which depleted city to place the cube on. Obviously, you’ll want to put the new good in the best scoring location for yourself.
This is good - makes this option useful.
