Brendan,
When you un-fasten the screws and then leave your mount lay on the side, are the screws tight then?
Mine were not - they were actually reasonably loose, as it should be expected of tapping properly done.
Then, what I saw as a potential problem was the fact that adjustment of the screw that was pressured by the mount under load (back screw) was changed with tightening of the opposite one, which should not happen and what I saw as a clear indication that the screws are not perpendicular to the surface of the post, so they were stressed radially, with the potential of damaging the threads by load weight (and even bending the screws under load.. remember, there is potentially 50 kp of load (telescope + counterweight) on one side of the the 200mm lever, held by that screw only 50mm away from pivot point.. which means more than 200kp load on post and screw thread.. a lot, especially if you have additional lateral stress.
So I decided to stiffen the whole thing a bit by adding the nuts. I simply like to have details done properly, no matter how simple or complicated they are
