In your 1st chamber, be it tank drain, or skimmer outlet, the water/bubbles usually get forced down to the bottom due to flow of the drain etc. So, if you now have to go UP and over a weir first, that makes the bubbles want to come out more there. If you went under first, you would be drawing the bubbles off the bottom, right from the direct drain stream, and only have one over baffle for the bubbles to escape.
Mind you, there is all sorts of scenarios etc. What may work in one sump, may not work as well in different sump config
