If they aren't a "marker" then they have to have at least a foot on the try line. Neither of them do, so they should have penalised EITHER for not marking square OR being offside, take your pick. Grabbing the jumper while playing the ball applies in both cases. There's 3 penalties there that were not awarded.

The Broncos no4 has his right leg stretched back, I’m guessing his foot is touching the line so technically he’s not a marker.
The other bronco is close to in front, certainly close enough for NRL refs (unless it’s us of course).
And yes he’s holding the jersey, but that never gets called.
What I don’t get is why forwards think it’s a good idea to keep pushing for 5m when there’s 3-4 tackles until they’re 1m from the try line... it makes the next play the ball so much harder with defensive line so close
