Pilot reported an aircraft had flown directly overhead approximately 150 feet above as they were still on the runway.

Narrative

My wingman and I flew VFR into ALM from in 2 military aircraft. We made 20NM; 10NM; 3NM; downwind; base; and short final CTAF calls for a left visual overhead break for RWY 22. After landing roll-out; I made an 'Alamogordo traffic; Aircraft X back taxi runway 22' call on 122.8. As I began my back taxi; a light twin flew overhead my wingman and me at approximately 150 feet while we were still on the active runway. The pilot of the twin stated; 'A back taxi call would have been nice.' I replied; 'Sir; we made a call on CTAF.' The twin pilot stated; 'I did not hear it on VHF. Have a great time.' I replied; 'Sir; a back taxi call was absolutely made.' No further communication between me and the twin pilot occurred. The pilot of the twin should have never released his brakes until he heard a Aircraft X clear of the active call on CTAF. The airfield has NOTAMS and AWOS stating that Taxiway work is in progress and that Taxiway A is closed between Taxiway D and A4 with barricades in place. There is no place to exit runway 22 once past midfield; all pilots flying at ALM should know that. I turned around at approximately the 2 board (7000 feet from the departure end); and the twin pilot should have easily seen two aircraft still on the runway. The aircraft made all appropriate CTAF calls. The pilot of the twin not only had a runway incursion but also created an extremely unsafe situation by departing a runway while aircraft were still on it. He could have easily collided with the aircraft if he didn't have the thrust available to climb or if he aborted his takeoff once on the roll.Of note - the tail number was given to us by others at the airport; who saw the event happen as they watched us land from the ramp directly adjacent to where the incident happened. We are lucky that the twin pilot had the ability to climb at the rate he did; given the airport elevation of 4200 feet. Had the pilot chosen to abort; I do not assess he would have had enough runway to stop on the runway before colliding with us. The twin pilot displayed reckless behavior; poor judgment; and a nonchalant attitude post overflying us.
