stupid slave cylinder question

[pitts12driver]

I have an LS3 and I bought a Keisler T56 magnum kit to go with it. The slave cylinder is green and is spring loaded to the extended position. So, my question is: does it somehow retract when filled with hydraulic fluid, or does it always ride against the fingers of the clutch?

Sorry if this is incredibly basic - all the other slave cylinders I've ever used in other applications were in the closed or compact position in the normal state.

thanks
