The difference between interned and uninterned symbols is that
interned symbols are held in a symbol table.  To reassure users that
interned symbols are garbage collected despite this, the documentation
explains that they are only weakly held.  Since uninterned symbols are
not held in a symbol table at all, the documentation has nothing
special to say about their garbage collection properties.
