Yes it does. Unless there are two clearly distinct offences. Which there aren't. A judgment is made of where on the continuum each offence lies. Sometimes it's allowed to pass - eg when a rider is chasing back on and there is no active racing, sometimes it is noticed and the offender is told to desist - eg if they push it a bit far, sometimes it's penalised by a fine, sometimes with a DQ - if it's aggravated or repeated. It's all the same offence, just different degrees.Having two levels of punishment for different severity of offence doesn't make it a "continuum".
That makes it unsurprising - to me at least - that events like this happen.
