The description for the ST_Cut function in Designer and online is the opposite of how the tool actually works. The description online says-
"ST_Cut(object1,object2): Returns the result of cutting object1 from object2 (spatial object)."
In reality object 2 is cut from object1 leaving only the part of object1 not intersecting with object2.
