I have simply avoided the scenario, but my WAG at the time was that the returning fuel had nowhere to go (quickly) and this affected the pump / rail pressure to make the mixture go either overlean or overrich. Luckily I was at a much better spot than you, and just descended at idle. I did try a power blip on short final and all I got was about 2000 rpm and very rough.
