He does use the word "independently", presumably to take this into account.

Right. But that is a big assumption of his position. If there is life on Mars and it is DNA or RNA based I would say the independence assumption is less certain. Then the author can go on happily assuming that the "filter" is probably behind us. Not sure why that is such a big thing though.
