Hummingbird, Multisite and Blog Template

If you have a multisite that is comprised of sites generated from a blog template that has hummingbird configured with assets deployed on WPMU's CDN, will all future sub sites generated from this blog template minify correctly and send assets to WPMU's CDN?

And if so, does each new sub site make a fresh set of remotely stored assets, or do all sites on the network use the same remote files?

All sub sites will be generated from the same theme, that uses the same stack of plugins.
