You explained it perfectly. You shouldn’t distract a bowler on an adjoining lane.
Something else I just remembered...
It’s rare but I’ve seen people get hurt because they didn’t wait for someone on an adjacent lane to bowl. Sometimes people try to use body-english, or celebrate, and move their whole body over into the next lanes approach. I’ve seen, more than once, a celebrating bowler get taken out by someone on the next lane who was just trying to bowl. It was not a pretty sight.
