Not in the context of an "over and back" signal for offside, though. The only mention of it is as follows:the back and forth signal is actually mentioned in the LOTG.........
When an offence occurs which requires a signal from the AR, the AR must:
• raise the flag with the same hand that will also be used for the remainder of the signal – this gives the referee a clear indication as to who will be awarded the free kick
• make eye contact with the referee
• give the flag a slight wave back and forth (avoiding any excessive or aggressive movement)
