I do not believe this is correct. My understanding is that the d-tron uses a
stepper motor (requires a specific set sequence to energize the coils and
turn the drive shaft) while the MM uses a solenoid motor (an on/off sequence
activates a plunger for one cycle which advance a ratchet turning the drive
shaft - hence the clicking). The key effect that you are interested in is
the same - neither system can constantly run-on if the  electrical input is
shorted - but the motor systems are different.

There was quite a lot of discussion about this a couple of months ago. You
should be able to find the original post in the archives.
