Yes, that was meant to be a feature but it is mainly an annoyance.
I've removed it from svn. You can set the xlabel to be blank on any
axes with
ax.set_xlabel('')

With twinx, you get shared x-axis, and because they are shared they
share the same locator and formatter. What you need to do is make the
ones on axes 1 *invisible*
for label in ax1.get_xticklabels():
label.set_visible(False)
BTW, for other uses, yo umay want to use the NullFormatter when you
want no strings. But this doesn't work with shared axes so use the
invisible trick.
