It's not even shorting it. Imagine if you took a plain battery and tried to charge itself from itself. You'd connect +ve to +ve and -ve to -ve: it'd do nothing.

I think the battery pack does clever things stepping voltages up and down: that's how it can give charge at the same 5v as it was charged itself. So in this case those circuits will be just burning off energy.
