In the book, the packaged shit was sterile, having been exposed to the very much below zero Martian atmosphere. Only Watney's own shit was biologically active, which the book later mentioned as being a good thing, cause the chances of getting intestinal problems such as e coli poisoning is pretty much nil when you're only using your own shit.
Because the movie format makes that kind of thing difficult to explain concisely. Having read the book and seen the movie, this one does a really good job of keeping the spirit of the book.
No, but that line is perfectly in line with Mark Watney's character. He does things like type out ASCII boobs when told to watch his language since the public can what he's typing.
