Didn't know that.  Am assuming there is no net at the back to prevent balls going too long which would explain this rule

Even with a net, the rule is in place generally to prevent people from hitting over it. Sometimes this is because there is a hole on the course beyond the net that puts golfers in danger, other times it's simply because they can't retrieve the balls from beyond the net easily.
