Why is third person singular denoted as second person plural (second_personp)?

Thanks for a great package.

I was wondering. Is there a reasoning behind second_personp counting third person singular pronouns?

Wouldn't it be better if second_personponly counted instances of "yourselves" for example and the third person singular count would be in third_person, with the third person plural (currently being counted in third_person) then being counted in a new function third_personp
