Indeed, I'm just as lost as you are :-(
For that reason, I'd be happy to get rid of this "use as the default
mode" thingy.  I.e. we should simply never inherit the major mode of new
buffers from the current buffer (if the global value of major-mode is
nil, then the default major-mode when creating a new buffer will be
fundamental-mode, and that's it).
