The thumb screw under the rear clamp can be adjusted to even things out. The rear clamp doesn't have to be real tight either. Finger tight on the thumb screws is sufficient. I've also used it to install rifle buffer tubes. Torqued the buffer tubes to 35 ft lbs easily. Don't even need the clamp. Wish I had one of these years ago...
You are correct, if you put very little force on the thumb screw under the rear clamp..
Tighten the receiver to the front via grip screw, then tighten the 2 top screws for the top bracket that holds the buffer tube. If a person then tightens the back bottom screw with any amount of force, it will pull the buffer tube down and possibly bind the castle nut against the end plate. I eliminated any possibility of binding by putting spacers between the back bracket and base. It is now permanently put on a perfect plane after tightening, eliminating any possible binding...It is quite easy to measure with a caliber when tightening the bottom thumb screw the amount of bend the bottom adj screw can create.
