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.

In what way have they reworded the clause? As far as I can see it is exactly the same as in http://www.opensource.org/licenses/bsd-license.php

You're right too. I mistakenly referred to a non-parameterized generic version of a "BSD style" license to make that statement, as here:

http://www.debian.org/misc/bsd.license

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.
