This info is from an atv but same principal just maybe different rpm/speed lockup
The wet clutch accommodates the task of getting the machine from a dead stop up to the speed at which the wet clutch shoes lock up solid. From this point on the CVT takes over the job of gear ratio establishment. This 'wet' clutch in stock configuration slips, when in high range, up until a speed of somewhere around 17 KMH (@10 MPH) is reached, at which point according to the motor's RPM it locks up.
When in low range this centrifugal clutch locks solid at the same RPM, but of course at around half that ground speed, or at around 8 KMH (5 MPH). *
Now because the wet clutch uses slipping friction to drive during low speed, sub-lockup operation, not only is heat being generated and wear on the clutch shoes, but friction material from the clutch shoes is being discarded into the motor oil.
