The real question here, is if the runway is long enough, can you leave your mate at the Holding Point, then lift-off and land straight three times down the full length, taxi back to the holding point and pick up your mate.
Making sure it was in the logbook for currency though... A 1 minute flight with 3 landings would raise an eyebrow, but is there actually an definition that says a flight has to be of a certain length... in effect you're doing 3 Wright Brothers' Kitty Hawks, and I am sure they were allowed to log it
