Maybe, but if you pronounce that fast you get the same word. The point was that the naked "du" doesn't suffice for the softer "dyew" sound. There has to be an "e" in there or some other additional vowel.
Im not seeing it (hearing it?)
Only if you say it slowly might it come out as "deyew", but im hearing "dyew" as "dew", pronouncing it as "Al-Doo-In" sounds to me the same as, for example, pronouncing stupid as stoopid :shrug:
