The docs say, regarding ${lookup } :-
If the lookup succeeds, <string1> is expanded and replaces the entire
item. During its expansion, the variable $value contains the data
returned by the lookup. Afterwards it reverts to the value it had
previously (at the outer level it is empty).
Which part of the docs were you reading, to get a different sense?
