The duplex scale on the piano refers to the non-speaking portion of treble strings. It can either be muted or left unmuted. If it is left unmuted its strings will vibrate sympathetically as overtones when other notes are played on the piano. On any given string, the duplex segment will not match the pitch of the speaking segment of the sting. (It cannot because these two segments are different lengths). If the tuner muted the duplex segment it was probably because one of the strings in this area wasn't seated properly against its bearing point and was buzzing. Another reason for muting this section would be if the piano sounded too resonant. By muting the duplex you can decrese the amount of decay time in the piano's upper register.
