Why do pistol manufacturers label strikee fired actions as DAO?

Sig labels their p320ca DAO and hk labels their vp9 as DAO. There are tons of others as we'll. It is misleading. The only thing I can think is it makes the firearms appear more safe

I think last time this got brought up it turned into a pissing match so 
The trigger both cocks (partially) and fires the gun on a pull, so it's considered double action. A single action trigger performs the single action of releasing the sear.

1. ATF has to agree with the categorization/labeling.
2. Glocks are DAO because pulling the trigger completes the "cocking" of the the trigger mechanism (the striker spring is placed under partial tension when you rack the slide). As the trigger is pulled, the tension on the striker spring is maximized and then the striker is released.
This is the definition of double action -- pulling the trigger "cocks/tensions" the hammer/striker spring and releases the hammer/striker.
3. I'll leave it to the SIG owners to explain why they are categorized as DAO (I don't own any SIGs).
eta: DS&FI beat me to it while I was typing.

Glock calls their action "Safe Action" for a reason. They know it's not a true DAO (ATF has to categorize the action somehow and can't create a classification for every variation) and it's certainly more than a SAO. Other manufacturers chose to just keep with DAO as it's just an academic distinction that really doesn't matter.
