Figured I might answer, since I'm quite certain this is the reason:

The PageStore class has an internal method pagefile that maps a page
name to its location on disk. This is run every time you need to read
any page, and therefore has a couple of optimizations for common
locations, such that if you're using one of a few specific strings,
the directory format string (the first parameter given to PageStore()
) doesn't need to be passed through the FmtPageName function.

One of these optimized strings is 'wiki.d/{$Group}/{$FullName}'. The
end result is exactly the same as with 'wiki.d/$Group/$FullName', just
faster.
