This doesn't make any sense. There is no "reduction" of a cryptographic hash that shows you anything other than "100% match" or "not 100% match". Essentially this is just displaying a random symbol along the side until the password matches completely.
EDIT: I'm surprised more people aren't commenting on this. It should be clear that if there were any way to tell if a match were "close", that would totally defeat the purpose of a cryptographic hash.
Essentially all this does it check the password (well, with extra meaningless false positives) without you having to press return.
