It used to be that this was not the case.  (In Emacs 20.2 I think.)

I agree that it would be better if they were the same, but I can't
think of a less disruptive method for having two major modes in the
same buffer, and to allow the usual parsing functions for each of the
modes to function more-or-less normally.

Another approach might be to have two buffers, one for each mode, and
to merge them into a third buffer.  Then each command in the third
buffer would be actually executed in one of the two buffers.  But this
approach gives difficulties in finding out how to merge the two
buffers.
