    Not sure about their wood block reference.

    Think about it. When you push the pedal the slave cylinder piston rod extends out moving the clutch release fork. The slave cylinder is filled to its maximum operating volume. When you release the pedal the piston rod retracts to its "clutch engaged" position. This position changes slightly over time as the clutch disc wears -- gets thinner from wear.

    So there's always fluid and possibly bubbles in the cylinder when the clutch is engaged {pedal not pressed}. To remove those last remaining bubbles in the cylinder you may need to retract the piston and rod to their minimum position -- end of travel. This doesn't typically occur during normal operation of the clutch. You are pushing the rod back into the cylinder as far as possible to push out those last remaining bubbles in the cylinder.
