When leaning in any direction the player body is teleporting in the direction of the lean. It feels like the body is on a grid system being moved between fixed nodes as the distance teleported is slightly further than the lean, but normally a fixed distance. When leaning in the opposite direction, the body will move back to what seems to be exactly where it was.
This is often noticed when looking down, particularly to check pouches and reorganise kit. It normally means when leaning slightly left to view the dump pouch on the left waist, the player body is moved in that direction. This leaves the headset is as close to the body as possible, instead of leant slightly forward, making it difficult to view inside the pouch.
I do not know if this affects leaning out of cover or round corners in combat, but I suspect it does, making taking cover more difficult.
