Binary packages have scripts (IIRC for .deb they are preinst/postinst to be run before/after installation and prerm/postrm before/after removal) that are run as root.

BTW the "unzip" part is also run as root, and a binary package can typically place stuff anywhere in your system (that's their job after all)... even if you used literal zip files they could still install a script in ways that would cause the OS to execute it.
