Yes I used the premium lane in Suvarnhabumi and then applied for a reentry permit. There is no difference, the premium lanes are just lanes located next to the other lanes, although separated by a wall. After getting the exit stamp, you turn left and walk to the same reentry office. If in need for the photoservice, you just keep walking "back into the country", then back to reentry office, then back to airside. They will let you do that.
