If you use any of those tools to do the installing, it doesn't matter 
whether the package itself imports setuptools or distutils.

You seem to be confusing distributions and packages.  If 'x.a' and 
'x.b' are package names, then each will have its own directory 
('x/a/templates' or 'x/b/templates').  If they used install_data to 
specify non-package data, OTOH, it'll be mixed.

That's why the recommendation is to use package_data or 
include_package_data; if both projects included their data using one 
of those two setup() options, they'll be fine.
