Why are the B-52 thrust levers advanced inside-out?
Note: Below is valid for applying takeoff thrust (part of the question), but it's now evident it wasn't the takeoff being shown in the video. Refer to OSUZorba's answer.



According to the video description, that B-52 belongs to the 2d Bomb Wing, which operates the B-52H variant.

According to the declassified B-52H manual, the pilot flying should advance all the levers "deliberately and evenly" to the thrust gate. The thrust gate is adjusted prior to takeoff, usually by the copilot, to limit the levers to the set takeoff power setting.

Initial reference to EPR (Engine Pressure Ratio) is not required. The pilot not flying then adjusts the proper EPR setting for each lever. So the standard procedure is close to what you have in mind.
