Even if it were true, we're referring to a landing in this case, not in flight.

The higher CG above the contact patch of the tire will make a high wing less stable than a low wing in the event of a tire problem. Also, a low wing (typically) has a greater distance between the mains, adding to (landing) stability.

I had a Piper Cherokee 180B several years ago. If you could keep the struts from collapsing, the "wide stance" and low CG made it handle like a go-kart on the ground - nice feature for high cross winds. That was about the only good feature of the plane - it had high fuel consumption, was slow and had a small CG envelope; although the elevator trim on the ceiling was pretty cool.

I had a Ercoupe 415D (with an O-200) as well, the natural landing stability of the wide gear, and low CG, was part of the original cross-wind landing technique - just land in a crab and let the wide, trailing link gear straighten the track on the ground (no capability of slips or skids in the original design).
