hard to say. it could just be that the note due them just happens to be large enough to require that they file a 13g. as the filing seems to say that they aren't necessarily holding any shares right now, but "Consists of Common Stock that the reporting person has the right to acquire by way of conversion of a security. "
I guess we'll just have to wait and see. like always.
maybe it was filed because the note is about to come due?
