That's the first time I've seen the Balmer RC but the explanation is ridiculous, he says the Kilmarnock player comes in from the side, the Motherwell player clearly is not making a challenge but because his foot comes off the ground and hit above the knee it's a red card, that's mental using that explanation there would be two or three red cards every game. . I also seem to remember a Celtic challenge which hit the chest but was classed as a yellow as it didn't hit the face.
Why wasn't the next one a red card to the Kilmarnock player it was well above the knee and there was brutality, it was worse than the Balmer one.
