After the change has been made the fully depressed clutch paddle is released and the partially depressed paddle is slowly released to allow for a consistently smooth shift.

I'll try to find a picture and illustrate it.
From my understanding, during actual driving, the clutch pedals are not used. I believe that ignition cut out is integrated with the transmission so that you can do "zero lift upshift" -- basically shifting by simply pulling/pushing the lever/pedal, no clutch pedal involved. This technology is used in higher level racing, such as the ALMS, and pretty common on motorcycles.

The clutch pedals are probably only used when stopping completely or accelerating from a standstill, i.e. pitting, or when you spin out
