For a reason. The rules-as-written are unclear, because of the vagueness of the word "several" not seeming to fit with simple logic, and making it impossible to accomplish a low-level task while stating the possibility of a more complex task (Staff of Fireball v. Staff of Fireball+Magic Missile).
In this case, a DM should choose which interpretation he prefers to use in his campaign. If you're playing strictly rules-as-written with no variation, you're going to run into a LOT of contradictions and vagueness.
