Roached sail reefing

This is an exciting chapter. When reefing, we rely on the topping lift to hold the boom when relaxing the halyard. With a perfectly triangular sail, the topping lift can always stay clear of the main leech. However, if we have roached sails, the topping lift will interfere with the sail when we tack. Before starting the reefing process, do I understand correctly that we should tighten the topping lift to hold the boom at the right level and, after the sail is secured, readjust (relax) the topping lift again to stay out of the way from the leech as the last step of the reefing procedure suggests?
