He wasn't shown doing that. So your operating on that assumption, which is an educated guess. Fine. But it never happened in the film. In contrast the Jedi Council is shown giving Qui-Gon orders as he leaves Coruscant; and Palpatine later gives Nute orders about what to do prior to the battle. So if there is no scene involving Palpatine tell Nute to pull out the blockade, it makes sense that he never did so.
