This is because as your releasing the clutch pedal the Clutch delay valve has a restrictor inside of it which is controlling the pressure to the clutch for engagement. So basicly the clutch is either engaged or disengaged and no inbetween. Without the factory CDV (with a modified CDV), there is no restriction in the pressure (fluid). This results in more of a direct control of the clutch pedal release and clutch engagement. From what I gather, a modified CDV will allow a more possitive clutch feel and control while shifting.
I think the idea of the factory CDV is to help prevent the clutch from slipping (being partially engaged), however, this leads to some jerky shifts when driving the manual.
Not really sure if anything I just typed makes sense... I have a modified CDV I'm installing on 23 Dec... I'll let you know how it works out.

Thanks for writing that. How do I get one?
