As Meikel said in his previous mail, 'do' at the top-level is treated specially: each form is treated as a separate top-level form. This is, for example, useful for defining a macro that defines multiple functions.
So what Meikel was really trying to say is that the reason (do (intern 'user 'bob3 3) bob3) works is that it is treated the same as (intern 'user 'bob3 3) bob3 This special handling only occurs when do appears as a top-level form, which is the reason why your other examples fail.
