Aqara P1 Motion Sensor assembly

Just curious, I have two already setup and in use.
Assembly per Aqara instructions. Wrong in my opinion.

Is there a reason why they instruct to stick the base over the battery compartment? I don’t care much if the Aqara name is upside down. You have to rip it apart to change the batteries and mess up the sticky.

Any reason I can’t stick it on the other side so the battery compartment is accessible?

Some mount them upside down so I assume motion is detected the same either way.
