It's also worth considering the fact that demons are, of course, tricksters and liars.  They may pretend to be thwarted by a Protestant so as to steal souls away from the Church and to keep them in heresy.

It's certainly a possibility. However, keep in mind that that's a self-serving sort of logic which some Protestants themselves use to explain the effectiveness of Catholic exorcism.
