I have no idea at all. I just found the setting somewhere and
thought it'd be a good idea.
But don't ask me what's for; device-mapper/LVM udev variables
are an arcane subject which I've yet to grasp.

Incidentally, a similar fix is needed for 10-dm.rules.
But I'll prepare a separate patch for this.

Cheers,

Hannes
