Not quite. If you put reverb before distortion, the resulting compression of the reverb's signal tends to make Godzilla like noises. Maybe fun for a special effect, but not my main tone, for sure.I think he means that the reverb with dampen the Marshally gains you would otherwise get. Yes, if you over-do it, there may be some loss but mine does just fine with it. You won't want to use an RV5 though.
