If the axle nut has been tightened/torqued, doesn't it compress the swingarm assembly at the rear axle thus fixing the position of the chain adjusters? So there won't be any forward/backward movement along the swingarm and the chain should be at the same slack when tightening the axle in place (sans stretching). Am I wrong in thinking this way?

Not sure if I'm interpreting your question correctly, but are you talking about how the chain slack seems to change when torquing down the rear axle?
When we adjust the chain slack, the rear axle is loose, allowing the swingarm to bow out to its natural position like a "Y" (this is an exaggeration). When we set the slack in this position, the rear axle and its slots are physically closer to the front sprocket by millimeters. Most people set the desired slack at this point, but when they go to torque the rear axle, it bends the prongs of the "Y" into the shape of a tuning fork, and now the rear axle is pushed away from the front sprocket by those few millimeters, thus giving them tighter slack than they just set.
