AF button Pentax 20D and Shake Reduction

When I originally set up my Pentax 20D to handle manual lenses some websites recommended that you turn the Custom Setting 13 AF Button Function to 1 (Enable AF). I have been using this setting for months to get an auto focus on the subject matter. The other day when I was pressing the shutter button to half way to focus on the subject matter, I wanted to activate AE-L at the same time, I noticed that the Shake Reduction hand appeared. If on the other hand I pressed the AF button to get focus then quickly pressed the shutter button, in one continuous movement the Shake Reduction hand did not appear.
My question is. By using this fast method of pressing the shutter after obtaining focus with AF button does Shake Reduction not work? This can lead to camera shake blurred images at slow shutter speeds. Is my thinking wrong and does Shake Reduction work anyway once focus has been confirmed.

I believe SR operates at the same time as the meter does. So I think the solution here would be to extend the meter time in the menu, or simply keep the shutter button half-pressed while you're focusing.

Thanks for the reply. I notice that the hand appears after a few seconds, I will just have to slow down.
