The reefing process is unchanged with a loose footed sail.
The reef clew lines will act as the outhaul when reefed. It is therefore important that there is an aft component in the pull of the tightened reef clew line (but not so flat aft that the clew wants to lift away from the boom), and that you have the required mechanical advantage to achieve the proper foot tension.
Making sure that there is no load on the sail while you are putting the reef in helps (sail luffing and boom supported), some larger boats have dedicated winches for tensioning these lines. An under-boom winch in combination with gooseneck stoppers works well here (if all lines are not led aft)
Also, as SD noted before, when tying up the extra sail, if you do so, it can be done without going around the boom, and will stress the sail less for it.
