The only reasons I can see for using a ND filter with flash are:

Shooting outdoors in bright conditions, and being constrained by the x-Synch speed of your camera and your desired aperture.

That's what Sailor Blue said:

"Outdoors...the ND filter is used to reduce the ambient light exposure."

Uh... a neutral density filter would reduce the over all exposure not just the ambient.

Oh poor thing, but there is lttle one can do about the ambient light, whereas one can often turn up the flash - that is the point.

don't patronize me, discuss why that would even be desirable.

The only reason I could see is to use a larger aperture than the lowest flash output would permit.

I'm not sure what you mean by that.  Basically though, if you're shooting outdoors in sun and you want to use flash at wide aperture you are going to have problems.  Due to sync speed you are going to be limited to around f/9 or f/10 at ISO 100.  If you want to shoot at f/4 or f/5.6 you are going to have to use an ND filter.

My apologies if that is what you were trying to say.

Even for that, you could back off the flash distance to the subject.
