Create an excluded block 8 mm high, create a sketch on the face, creating a 6 mm high square, then extruded this through the block. Now increase the height of a block to 10 mm, then back to the sketch of the face and increase the height of the square, to 9 mm This excludes the whole height of the block of 10 mm rather than than 9 mm from the updated sketch ?

One would assume that the extruded square would take the dimensions of the sketch.

Sketches and bodies are not associated in the current release version. Changing the sketch after the fact will not affect any bodies created from the original sketch. The history based parametric modeling update, currently in public beta, will address that.
