Mutlics doesn't separate the name and the data.
It did do something really interesting tho; segments could have multiple names.
Given a segment "foo", you could "add_name foo bar". "foo" and "bar" now refer to the same segment, much like a UNIX link. However, if you move the segment to another directory, the names follow -- they are part of the segment metadata, not entries in the segment's directory.
This was leveraged by the binder; when binding an executable segment with multiple entry points, the binder will add the entry points to the names of the segment, and the shell would select the correct entry point based on the name.
