With all due respect but this statement is the one which indeed is just making it up.
The law is clear the only cautionable offence that is downgraded is SPA. Any other cautionable offence (which you limited to just two with no basis in law) can still be cautioned, even if it happens at the same time as a SPA, or interfering with.
Only a couple of weeks ago we had a double caution where the first one interfered with a promising attack but was also either not respecting the distance or general USB. Are you saying caution for not respecting the distance is circumventing the law?
I was talking about the act of committing a foul, so didn't include failing to respect the distance.
What I disagree with is the "general USB". The law is crystal clear that if you play an advantage for an SPA offence the player is not cautioned. For the avoidance of doubt the text is "if the offence was interfering with or stopping a promising attack, the player is not cautioned". It doesn't say that you can circumvent this law by making up a random "general USB" caution to get around it. SPA will generally just be that, shirt pull, pulling a player back by the arms or shoulder, blocking someone off, etc, it will very rarely fall into any of the other cautionable offences.
