It does, and Debian Policy says it must. That information ends up in
/usr/share/doc/${binary_package}/copyright where ${binary_package} is the
binary package. For instance, the dbus source package produces binary
packages that include dbus, dbus-x11 and libdbus-1-3, so its
debian/copyright gets copied to /usr/share/doc/dbus/copyright,
/usr/share/doc/dbus-x11/copyright and /usr/share/doc/libdbus-1-3/copyright,
among others.

In rare cases the binary package copyright file is not identical to the
source copyright: if a package foo has a GPL part packaged as foo-utils
and a LGPL part packaged as libfoo0, it would be valid to list both GPL
and LGPL in debian/copyright, only GPL in /u/s/d/foo-utils/copyright
and only LGPL in /u/s/d/libfoo0/copyright. However, in practice
maintainers don't make use of this, because it creates extra work for
little or no benefit, and carries a risk of accidentally providing
incomplete or untrue copyright/licensing information.
