With a normal shock, that return pressure when you hit a pot hole is pretty much contained to one wheel well. With a hydraulic suspension like ABC, some of that pressure goes back into the system which burdens the hoses.
I say drive and don't worry.
Here's a great summary of ABC on Wikipedia:

Actually the new procedure is to filter instead of flush, which is using the same fluid but cleaning it. This is done by installing a new 3 micron ABC filter, running the rodeo program in SDS twice and then replacing the filter again. This ensures that all of the fluid in the system traverses the new filter and gets clean.
