I still don't understand what happened here

For those of you said this is not a backcourt violation read the text and explain please I'm genuinely curious

Seriously what in the world was Wemby trying to doing here on OG

An alternate angle of Wemby's kick with the game timer Doesn't look as intentional as from the other angle first posted

What Do You Think Wemby Was Saying Here To The Team

OG didnt know how to end the live

Was Wemby Trolling Here or is He Angry Whats he mean by this
