That makes sense to me!

Thanks for the correction.

Your deduction is not 100% valid. 1/4WL can be a BIG problem and
worst case for matching.

I guess MFJ is technically correct but confusing. For instance,
assume a 50 ohm antenna and 1/4WL of 600 ohm open-wire line. The
"resonant" impedance seen looking into the feedline would be 7200
ohms, outside the matching range for a lot of MFJ tuners. Half a
century ago, we called that the "anti-resonant" point (akin to a
parallel resonant impedance). Most amateur radio operators should
substitute 1/2WL for 1/4WL in the above MFJ manual quote to avoid
thinking 1/4WL is "no problem".
