Actually no. I looked closer frame by frame.
The instructions are closer to the back (the whiter part of the tube), that's the correct way around.
When he fires, a fire appears behind him, that's also correct.
The problem is that that "fire" is backblast, which he does not account for. Backblast can be lethal. These things are "recoilless" because they exhaust all that energy backwards, it's not closed off like a pistol or a cannon. You're supposed to leave tens of meters behind you in a cone free to account for that. This idiot fires his RPG in an enclosed space upwards so the back vents out to his little hole.
