+1 to @LiQuid_cOOled 's suggestion that you should create a sensor group that treats it like a single sensor.
you might then also consider using this blueprint: YAMA - Yet Another Motion Automation (Scenes, Ambient Light and some Conditions )
the blueprint lets you specify scenes, which let you set the brightness to what you’d prefer. as well as day evening and night times and scenes to have different brightnesses.
you have a possible bug in your current implementation that you are restarting your 2 minutes only if you get another motion event… which means if you keep a continuous motion for 2 minutes, the lights will shut off. usually the approach is to wait a period (2minutes in your case) after motion stops, not after motion detected is started… again, because continuous motion will not necessarily trigger another motion event.
if you don’t wish to create a sensor group for some reason and also want to keep with your existing automation, you could also solve this by using 1 automation instead of 3. just put all 3 triggers in the trigger block of a single automation. that way any motion in any of them restart the same automation delay.
