Hm...  well, after fiddling with this a bit more, I see that it's
describing all these minor mode bindings in the context of the buffer
you were in when you called the description command.  I think that's
correct.  If you have these commands bound to `<' etc in that mode, then
that is what the help command will say.

So the form above will give different results when run from, say,
*scratch* and from a special mode, and that's fine.  Closing.
