Not quite. At least in my case, the toilet seal prevented anything from getting into the coach but I learned it will sure back up through the vent pipe and pour on to the roof.
Fortunately, I had already dumped, filled, dumped again and was filling for another strong flush so the water wasn't as bad as it might have been.
