It turned out the guy from the alignment center told me the total rear toe (left + right toe, shown on the left of the display) was the rear left toe and the thrust angle (shown on the right of the display) was the rear right toe. So because of that I was thinking left toe was suddenly +0.33° and right toe was +0.03°, while in reality left toe was probably +0.13° and right toe +0.20°. So no problems at all with the beam mounts moving.
