Weird way to do the six block puzzle

[Tsunya(2⁷2A)]

I was aiming for the actual solution of the six block puzzle but somehow cleared it in a way I didn't understand.

I wonder if it is a bug or something.

What do you see as 'actual sollution'?

Any cube net that's not already displayed works afaik

The video shows that I solved it by using a J piece which only has 4 blocks and that should not be the case

Could anyone explain what happened there or is it just a bug
