We also have judgement calls on where a disc went out of bounds or if it cross inbounds before ending out OB. These calls can have a huge impact on the lie, and if in doubt, benefit goes to the player. How is jump putts any different?
No one throws OB to try and get an advantage. No one intentionally throws OB. There are a lot of differences.
It really is simple, stay behind the marker at all times. Easy as pie.
