Ok I will try another scenario :)

Imagine again products A, B and C and a common library. The products are in
a stable state of development and track a stable branch of the common lib.
Then imagine an important security fix gets made to the common library. On
the next pull of products A, B, and C they get this fix for free
because they were
floating. They didn't need to communicate with the maintainer of the common
repo to know this. In fact they don't really care. They just want the
latest stable
code for that release branch.

This is how package management on many linux systems works. Dependencies
get updated and all products reap the benefit (or catastrophe) automatically.
