That's interesting and odd, Arc. So basically from now till early December?
I could understand if it was to prevent a stay on Friday or Saturday nights but why block a Tuesday night?
The only thing I can think of is that at guest departure, Mousekeeping has to do a full cleaning of the room. I'm not a hotel guest at Disney but I think Mousekeeping is limited/optional DURING a hotel stay so not as many rooms need the full cleaning on any given night.
Example: 100 room hotel, filled to capacity each night with guests doing 1-night stays. Requires 100 full room cleanings per day. Same hotel but guests doing 3-night stays requires only 33 full room cleanings per day.
So I guess it's not to overload the Mousekeeping resources available.

PS - Disney has the data on the number of 1-night stays so it must be significant enough to trigger this change and keep Mousekeeping quality/volume where they want it.
