[Usability] Mistake in the HIG?

[Steven Garrity <stevelist silverorange com>]

Figure 3.17. "A save confirmation alert" in the HIG (2.0) has three 
buttons, but it seems that the keyboard shortcut character for the first 
two buttons is "C".

"Close without Saving", "Cancel", and "Save"

Is this a mistake?
