That would just expose framing, or siding, or sheathing, or something.
You need the 2" clearance above a roof, etc., but, for a foundation, you want the stucco/metal lath/paper/paper/sheathing/foundation weep screed to extend over the foundation/wall joint.
With the vertical side, you want the screed to be adjacent to (approximately 1/8" - 1/4" from) the brick/wood/whatever to allow for a caulk joint from the screed to the other material. The stucco is plastered up to and into the screed, leaving the 1/8" - 1/4" joint open to accept the caulk/sealant.
