Sure, it would in many cases return the query used in the view (I think it is possible to delete the RDB$VIEW_SOURCE and still have a working view, though that is rarely desirable and probably not something Łukasz has to worry about), but it doesn't return FieldNames as defined in

CREATE VIEW [ViewName]([FieldNames]) AS ...

just whatever is after AS.
