DAVID 5.3 is using the same algorithm, but when you are scanning with one cam you are using camera - projector - object triangulation to calculate 3D points. With two cameras in stereo mode you are using camera 1 - camera 2 - object triangulation.

I've generally had better results scanning in extended mode than in Stereo. By Better I mean scans that align better and overall require less work to get to a finished fused mesh. I find that in stereo, even with outlier and error turned almost off, David has trouble scanning steep or recessed surfaces (I know theses are difficult anyway). When I scan in extended I can get more of these features and fewer holes.
