The comment would be the same as my first thoughts: It's dumb to obtain combustion air from a crawlspace, hard to believe the code allows it, but it does, however, it must be kept in mind that code is minimum requirements - or it this case, not "requirements", but "allowances".
Then you immediately get back to reality and add: Remember, code is minimum, code does not address common sense or basic construction practices.
Common sense and basic construction practices would say something like: It's dumb to obtain combustion air from a crawlspace.
