Yes, the sensor throws a matrice over the pupil to trace its movement, correlating that with the layout of the focusing points in the viewfinder.
Historically, some opticians have expressed concern about the idea of having beam so close to the eye but it appears nothing untoward has been reported.
It is the 'flare' of the beam that people interpret as reducing contrast. Ideally turn the whole silly thing off and concentrate on the image in front of the camera rather than the technology trying to do everything for you.
