I believe that when they mention 'Butted Tubes' they are stating that the frame is built with tubing that uses the butting process to reduce frame weight. If you have a look at Reynolds tube decals, they often mention that some or most tubes are butted - meaning that the stated tubes are mainly double butted or butted at each end and as unworthy mentions, the seat tube is butted at one end. The frame has butted tubes.
