The method getTotalRevisions() is implemented like this:
public int getTotalRevisions() {
getSignatureNames();
return this.totalRevisions;
}
Here the totalRevisions member variable is set to the number of signatures
as a side effect during getSignatureNames(). Thus, both calls have the same
effect, they actually call more or less the same code.
That being said, though, there indeed can be more PDF document revisions
than the signed ones, for backgrounds read this stackoverflow answer:

getTotalRevisions() ignores those other revisions.

Michael
