Changing the Z steps and multiplier changes distance

On a maestro with the last beta,
I ran across a weird issue while troubleshooting another problem with a print.
In my setup, I normally have this:
M92 X80 Y80 Z400 E837 ; Set steps per mm M350 X16 Y16 Z16 E16 I1
and the printer works fine.
When I changed it to this:
M92 X80 Y80 Z25 E837 ; Set steps per mm M350 Z1 I0 M350 X16 Y16 E16 I1
For full steps, and trying 1/4th steps (Z100) and 1/8th steps (Z200) each change how much it moves (manifesting with really slow speeds).
I have a BLTouch that because it moves slower and less distance, when it is trying to home it can only clear the BLTouch fast enough on 1/8th steps.
An example on full steps of it moving down while probing and when the bltouch is triggered it continues to move down until it is errored out: https://www.youtube.com/watch?v=sWSr2CEH2sc

My deploy probe script: M280 P64 S10
