In modern aerial combat environment that maneuver is as dumb as Maverick's "I'll hit the brakes, he'll fly right by" maneuver from Top Gun. It's the equivalent of turning off your engine at the top of a zoom climb in AH. If you have any doubts, you can ask one of our resident fighter pilots, like eagl, heater or mace.
I would say yes. Doing a tail slide in real combat is a very unwise thing to do.
