I think I see why this was put in the rule.

It is possible to get a SP certificate, flying only fat ultralights, that
could not do 87 knots in a dive. OK, that is stretching it, but take that
as truth.

The FAA does not want you to get in a fast (88 to 120 knot) Light Sport
Plane, without having a signoff that shows you can fly a faster airplane.

The other stuff, I think Todd has nailed it.
