'easter rose' blooms on fourth of july... experts really not that surprised

Okay, I've long bragged on the merits of the Japanese kerria as a tough and good-looking shrub for filling in those hard to plant part sun/part shade places where everyone seems to think only a nandina will do. And one of those bragging points was that it often blooms again "sporadically" throughout the spring and summer. But this shrub on Duke's west campus (see my post from earlier this year) really has me jealous. My home-grown version isn't coming close to another flush of yellow flowers.
