Well, there's a connection of Waiter and Rillaine, with their representive Vocaloids, and the fact Waiter was born from the Mirrors of Lucifenia, the Vessel of Vanity, and Rillaine committed the Deadly Sin of Vanity.

and since Irregular is called Waiter's other half, people assume Irregular is to Waiter like Allen is to Rillaine.

There's also some irony involved, like how Rillaine was a princess; Allen was a servant

and Irregular is going to become Master of The Heavenly Yard, while Waiter is just that-- a waiter.
