Yup, the code here is quite finicky.  That's why I added a remark in
tex.el about what `file' does just above the lines of code you cited
above:

    ;; `file' means to call `TeX-master-file' or `TeX-region-file'

So with %s you get the file name without extension and with %t you get
it with extension.

Eventually all the extenders should be documented in the manual so that
people actually get to know and have a chance to use them.
