You're right; <strike>but they've even reworded that clause.</strike> I'm correcting my grandparent comment to reflect reality, with a note that it's been changed.
My initial writing was also confusing the 'simplified BSD license' used by FreeBSD (without the "no-endorsement" clause) with the full classic BSD.
And this is another reason to hate license proliferation. Remembering all the "BSD, except X" variations is an error-prone pain. Let's be coding and sharing, not lawyering.
