Furthermore, fontspec prints the specification in the log, and there is nothing in there which would select alternates. This rules out fontspec as the culprit.

Don't take what is printed in the log with great confidence, bugs exist.

For this particular case, because two successive posts suggested a
change in XeTeX behaviour which I highly doubt and since I don't have
the font myself I can't but suggest what I think a strong way to rule
out engines bugs; test with a different engine. I'm not asking anyone to
switch to LuaTeX (though I consider this a desired out come), I'm only
suggesting a step in debugging this particular case.
