How can someone have a 3rd or 6th great-grandfather? Each person only has 2...a maternal and paternal, right?

You have four grandparents, eight great-grandparents, sixteen great-great-grandparents and so on.
What I assume
rcarlton means by 3rd great-grandfather is three further generations before his great-grandfather, that is his great-great-great-great grandfather.
