What's wrong with the picture? They used the same technology in UCL.
There are two Ecuador players next to the GK. One is on the ground and his right foot is in front of everyone (offside), the second is jumping and heads the ball next to the GK. Ball then drops a couple times on the ground and the guy that was offside on the ground comes back and heads it in the air, then the guy that was heading the ball first next to the GK assists for the goal. Offside was called because the guy on the ground came back and played the ball before the assist
