Abloy door hinge adjustment (Finnish manual).

Hi, I'm having trouble understanding the following the guide for the lateral adjustment of the door panel (Ovilevyn säätö sivusuunnassa) in this guide…

My door has 4 hinges, so it's one of these…

1. Loosen all of the screws on the bottom 2 hinges, and turn both adjustment screws.
2. Loosen the bottom 2 screws of all the hinges and turn the bottom adjustment screw (of all hinges).

The translation seems to indicate 1. but that doesn't make a lot of sense as that would distance the bottom half of the door unevenly to the top half.

What do you think? Do yo perhaps have experience with this?

Thanks.
