VRF indoor continues blowing air even when the set point is reached

Generally those inverter systems are designed to work all the time. It doesn't mean that the compressor is working, but the fan will be blowing the air as long as the system is turned on by the user. 
When it reaches the set point, it will simply close the expansion valve and this would be analog to the "stand by" mode. 

That's how it should work, It is according to the VRF design. 

It is one of the greatest advantages of the inverter-based systems, where they save energy and provide much more accurate climate control.
