Tom is not running a parallel straight line, Toms hands are not being shown from a "directly" in line of the play "fixed camera", the distance of the pass is less---i could go on.
Obviously the linesman having the best view in the house means nothing, best fixed position relative to the passer with a human viewing resolution of 576 megapixels, compared to a non fixed position behind the play camera with an at best resolution of 4k(maybe 8k downscaled not sure)
I've seen it before and i'm sure many other fans also, sitting in the crowd being directly in line with a pass and seeing it obviously being forward but no-one else in the crowd batters an eyelid.
Ref or Linesman in perfect position to adjudicate any call i will back them more often than not, not in a perfect position have no problem calling their decision making out.
