Phosphorus (III) oxide is unlikely to be reacted directly with a base. In phosphorous acid, the two hydrogen atoms in the -OH groups are acidic, but the other one isn't. A basic oxide is an oxide which when combined with water gives off a base. The ‘oxide and water’ approach allows the focus to remain on the main teaching point without the need to cover another set of reactions (although these could be covered with an appropriate group of students). In a typical Wittig reaction, the ylide is not isolated but reacts directly with the carbonyl compound (aldehyde or ketone) to produce a betaine which transforms into the unstable four membered ring oxaphosphetane. When reacting with water, these compounds form oxacid acids , but if they are in the presence of hydroxides , what is formed is a salt and water.
