Need some advice on my config files for bed levelling

Hi,
I do bed levelling with two screw.
Everything is ok, but could you check my file if I do the job correctly ?
I have a BLTOUCH, on coreXY with dual Z motors.config.g

I have to do a G28 Z or a G30 Z0 at the end of bed.g ?
I would think so, since any tilt correction would have moved the Z0 position at the center of the bed.
