He might not actually have the tooltips - I see in my install that I only have "TPL_BACKGROUND_TOP_DESC".
(Same for all the tooltips in the Template Specific section - they are fine in all the other sections though.)
Presumably an issue related to one of the language .ini files somewhere ?[EDIT #1]
Yep - looks like this one is either incomplete or truncated :-
It just contains :-

I'll grab the Site Shaper version of the download, and see if that has a more complete version than the one in the standalone download version I used.[EDIT #2]
Nope - looks like all the download packages (Joomla 1.6 - 2.5/Current, Template/Site Shaper) have the same file.
