Cocoa powder question

[jvgymnast]

I've just gotten a new cookbook, and I noticed a recipe that uses Dutch process cocoa powder with baking soda. However, I thought the match-up was supposed to be regular cocoa powder with baking soda and Dutch process with baking powder.

Other ingredients in the recipe are all-purpose flour, cake flour, salt, butter, sugar, egg yolk, vanilla and chocolate chips.

Is the recipe wrong to pair the Dutch process with baking soda?
