Maybe setting first then jointing removes the set you just applied,
especially if the teeth are very uneven or a lot needs to be removed
to get a straight or slightly breasted edge along the teeth.

Personally I do it in the order:
 - joint
 - sharpen (one pass from each side)
 - set
 - lightly stone to remove burrs/uneven set
 - test cut
 - smile at what an improvement I have made
 - tell family members how clever I am :-)
