I found a post here where @dc42 asked if the tool offset was set in the correct direction but it seems nobody responded. So maybe the implementation is incorrect and sets the offset in the wrong direction. This is also consistent with my observations, as when I manually touch the surface with "G30 S-2" at Z-50 and run G1 Z0 the head moves to the upper end stop instead of staying in place as is should. When running G1 Z-100 the head touches the bed again. This implies that the offset is added in the wrong direction.
