I won't say this is impossible, but in general it hasn't been true for a long time in Gentoo. Old libraries are left behind until you rebuild the things that link against them (that's what emerge @preserved-rebuild does). When used correctly, subslot dependencies in ebuilds avoid the need for even that additional step.
