Without the rule, offensive players could hover near their opponents' goal even when the play is on the other side of the field, with the hope of a long pass and an easy goal. The offside rule applies at the moment the ball is touched or passed, not when the ball is received.
Any players joining a ruck/maul or scrum from in front of the off-side line are offside and their team will be penalised. At a lineout only players in the line (normally 7 per team), a receiver (often the scrum-half) and a thrower (usually the hooker) from each team are allowed within 5 metres of the line.
