Well in my view Segmentation is cutting out the whole picture in one piece of timber to make it look like intarsia. But Intarsia is actually made up using several different timbers cut into small parts/pieces to form a whole picture. (thats what one eyed intarsia people say anyway)
In Bobs case it is segmented woodwork- because as it has been said, it is cut up and glued together.
