The unclog scheduler is just going to print a purge sheet on your schedule: the printer treats the purge sheet as a "normal" print so the printer is going to print normally and (as with any other print) the head will return to parked position when the print is done.

So the head is still going to stay in parked position between unclog/purge cycles.  The difference is, if you purge on a 3 day schedule, the ink sitting on the surface of the head will only be 3 days old at most and that prevents the drying out problem.
