After they were vectored off the trups RNAV STAR to dca for spacing the flight crew of a B737-800 assumed that a clearance 'direct to trups; resume the STAR' included the clearance to resume descent on the arrival. ATC disagreed; believing they should have maintained their last assigned altitude independent of the STAR restrictions.

Narrative:
[We were] conducting the trups one arrival. ATC had taken us off of and back on the arrival a few times for spacing. We were then cleared direct trups intersection and resume the arrival. After passing trups intersection we continued the descent to cross frdmm at 8;000 ft. As we were passing 10;400 ft controller intervened and advised that we had not been given a new altitude and then cleared us to 9;000 ft. No conflict was noted by the flight crew or indicated by the controller. I suggest when giving a clearance to resume an RNAV STAR that the controller verbalize either a maintain altitude or give the clearance to descend via the arrival to avoid any miscommunication.
