As everyone else has said, it sounds weird.
The FAA Airplane Flying Handbook calls for 1.3 Vso or the manufacturer's recommended speed to be used on final. I see no mention of adjusting airspeed in the face of various headwinds (power, yes).
Perhaps the most politic way to approach the situations would be to say , "Hey I was re-reading the FAA Airplane Flying Handbook and saw in chapter 8 where they discuss landings, and it says blah, blah, blah, but you want me to teach blah, blah, blah, so I must have misunderstood something. Can you help me understand how your way is actually not in conflict with the Fed way, cause I really want to do it right."
