I might have some hope of understanding this with an example. 

As detailed in the documentation, subrepos are only pulled when
necessary. That means pull on happens in a subrepo when we attempt to
*update* a subrepo to a revision we don't have locally. Nothing at all
happens with suprepos when you *pull* at the top level.

Not surprisingly, Mercurial is different from SVN here: SVN has no
notion of pushing a pulling.

Again, I have no idea what this means.

When we pull in a subrepo, we always do a full pull.
