How important is caulking along Z-flashing

My Hardie siding contractor and I have a running dispute over the proper installation of Z-flashing over windows. He insists that it should be caulked, but the Hardie installation instructions specify that it should not be caulked because it needs a drainage path for inevitable water infiltration behind the siding laps.

He flatly refuses to rework the caulked flashing. Is this a big enough problem to be worth having someone else rework it? Am I going to have deteriorated siding or water problems in a few years because of this? After all the other problems we've had on this job, I really just want to be done with this guy and get him out of my life.
