That is really poor, much more obvious a mistake and the referee will be in real trouble. Not just a have three weeks off mistake, but potentially something that will be held against him for years, even if just subconsciously.
This is why it is so important, especially at L4 and above, that you know law inside out. Kind of reinforces my previous comment in response to
@Ben448844's question as to why referees are suspended for these mistakes. This will cost the clubs a huge amount of money, the cost of the home team staging the replayed game, the cost of the away team travelling to the same venue again, and the cost of the three match officials. You can't make really, really poor decisions like that and expect to not get sanctioned.
