From the guidelines: "Question dialogs (using buttons) ask users a single question or to confirm a command, and use simple responses in horizontally arranged command buttons." The key part being use simple responses. They fail on two parts, it could have just said yes/no like 99% of dialog boxes out there. Secondly it changed the order from standard. On the next guideline: "Whenever possible, assign unique access keys to all interactive controls or their labels.". These buttons do not assign access keys. Agaion y/n are the common ones here. They've literally went out of their way to create a more confusing dialog when the ismple confirm dialog would have been perfect.
