Dave,

My choice was to go flush with the butt rib. My reasons included: 1) it will not be a watertight seem either way - couldn't think of any advantage in doing an overlap; 2) with an overlap it may be possible under certain circumstances to have pressure on the glazing at the juncture; aand, I wanted to avoid that possibility.

They are done both ways so I think a person has to think it through and decide on what they are confortable with.
