In this case the 月 makes first 濃茶, and then 3 薄茶 are made. The 月 also drinks 濃茶, so they have to go to the waiting 畳 just after they sort the bowl, and then go back while 拝見. Before dumping the water, swirl it around like in 天目. First 花 will clean 棗 and put it in 火窓, second one will switch positions (茶杓 on 水指, 茶入 on 棚, 棗 in position). Third one also has to do something, I think, but I forgot what it is. There's 拝見 of 茶入 etc., so no それい with the 水次.
