Because that is what works best for a conventional homing where the
switches are on the axis. Turn on the machine, home, and you are right
back where you were the previous time.

You are actually trying to home by probing, which is a somewhat
different thing, and is causing the problems you see.

Rather than using the home sequence you could make a button that calls
a probing sequence to set your homes. This can properly take account
of the variable lengths of your probes (or tools, as they are normally
called).
(you would need to use a G-code output to twiddle the
halui.axis.N.home pins, and configure so that the axes all make as
homed at their current position)
