I think they talk about the link editor (static linker) chosing the
symbol version, and not about what happens at run time.

Old binaries originally linked against glibc without symbol versioning
would also use sem_init@@GLIBC_2.2 as the result, but that would result
in breakage because the type sizes are different.
