The analysis presented models the contact as a sphere and includes the heat distribution within the sphere. It does not assume infinite conduction as that would give zero temperature rise.

To accurately model the temperature rise in the contacting stylus we would need to know the thermal conductivity of the cantilever and especially the junction between the cantilever and the stylus. In the absence of better information I would defer to the measurements made by Van den Hul which gave about 40 - 140 oC rise in diamond temperature.
