That section of policy talks about _dependencies_ whereas the change done above is a _build-dependency_. It is a common pattern in Debian to provide a virtual library development package. Purpose of the section above is to ensure deterministic install (non-random install) but that is ensured by the maintainer of the library package only having a single package available in any suite at a time providing the virtual package.
