@PubUser, that might be a correct description for one airplane or variant, but certainly not for all. On "my" type when flying a VOR approach in approach mode the autopilot or flight director will be following a database derived final approach course and glide path. Actually the same thing as using LNAV/VNAV, just with the added bonus that there are active warning calls and the procedure is identical to a normal ILS. VORLOC would follow the radial and leave the vertical path to the pilot, however that procedure is not used anymore.
