Hanging lets you know which shades from Create Shade are fake if you just target them. The "real" location of the enemy will show up as a red tile / unable to target, as Hanging cannot target enemies with an ally next to them.
 
The shade being on top of the enemy's location counts as "being next to" them, so. Technically working as intended, just an oversight.
