Pardon me if I missed mention of this in a previous reply, but the PAPI and glideslope indications below 200' will only coincide if the aircraft's glideslope antenna and the pilot's line of sight are also aligned when in the normal approach attitude, and then only if the PAPI and glideslope angles and placement are both exactly the same. Given these variables, it is difficult to provide a generic answer for every glideslope / PAPI / aircraft combination. The technical specifications available at the above website will give you an idea of some of the design and installation criteria, if you have the time and inclination to read through them.
