I think you're looking for a level of certainty and specificity that the LOTG generally doesn't have. It's unreasonable to expect the offender to have moved away before the offended-against team is ready to go - and the placement of the ball is usually a good indication that this time period is over and the offended-against team is ready to start playing. So that's a good indication that the other player shouldn't be actively obstructing the kick any longer. But that's a casual practical refereeing tip rather than a specific law.
