Boy are you skeptical!

He's got a right to be, because the impedance changes with frequency. It is
not unusual to see an "8 ohm" speaker dip down to 5 ohms somewhere near the
cabinet resonance and rise up to 25 ohms or more somewhere else.

The ratings are really just guidance for what speakers are safe to use with
what amps, and they are reasonable guidance. They are not gospel.
