NFHS Mechanics

I have seen these often.
-Official blows the whistle for a foul. Then takes a Slooooow walk to China and reports the foul while walking.
-Lead official calls a foul on the Offensive team. Takes 1, maybe 2 steps off the endline to report the foul. No switch. Goes back to the location and inbounds the ball as the new Trail official.
-As a Trail official, bounces the ball across the lane for a throw-in.
-As a Lead official, bounces the ball to the thrower for an endline throw-in.
-Ball goes Out of Bounds. Blows the whistle. Does Not use Signal #2, stop the Clock. Just goes straight to signal # 6 and points the direction.
Are these the new trends?
