In the mechanism - yes. But if you run the reaction acid gets diluted, so if it wasn't in a large excess reaction will stop. There is no error in calling it a catalyst when applying simple and rigid definition of catalyst. Unfortunately, chemistry hates simple and rigid definitions, and you can be sure almost always you will find a system that doesn't fit.
