That refers to purchase and usage – not registration. They make that clear in the last paragraph that you forgot to quote, where it says (under 3.4)
“It’s acknowledged that the disabled wheelchair user may not legally be allowed to have a vehicle registered in their name. In this circumstance, we would expect supporting evidence to be provided to the supplier.”
Under normal circumstances (ie, his wife isn’t underage or otherwise legally unable to register a car), the car has to be in the wifes name. Only if the disabled wheelchair user isn’t able to register the car in their name due to legal circumstances, is someone else (given sufficient evidence) able to.
