The name promises the treatment an animation gets from the same spelling: pixels tested against the ground rather than against the standing gradient everything else uses, so that the artwork reads as lying on the terrain. No drawing path consults the structure’s copy.

With the flag set, the animation’s pixels are depth-tested against the ground plane instead of against the standing gradient everything else uses, so the artwork reads as painted on the terrain and whatever stands on the cell covers it. The same choice is made for the copy drawn under fog.
A Tiled=yes animation takes a different drawing path that never reaches this flag.
