You are almost looking at it as unloaded blade.
Look at the other extreme. Dead shorted to 1 RPM.  It is still turning, so it must still be making a tiny bit of lift (maybe not- but you get the idea).  

A couple RPMs before cutin, the blades are running faster than the design TSR.
A little bit into stall, the blades are running slower than design TSR.

The say 5 degrees at the tip is fixed, but the angle of attack is related to the RPM of the blade.

It sounded better in my head,
