That's probably true, but it may depend on your other completion settings.
Completion usually errs on the side of giving you too many choices, when
there is ambiguity.

I think the doc for CDABLE_VARS predates the ability to refer to dirstack
entries with tilde-notation ... "as if it were preceded by a `~'" really
means "look it up in the named directories table and use the value of the
parameter".  Since "3" is not really a parameter ...  Anyway, I believe
this is a case of the implementation outrunning the doc.
