Quote from StewartFisher :

His flag is American...for some reason "could care less" is the way they say it across the Pond. Makes no sense to me either

no.. its just people that dont pay attention to what he is saying (apparently its also incorrect to use "they, them.. etc, and replace with he/she)

in all, he could have said that meaning that he could care less about it, and could not care less of what it looked like/how it worked ..
