I would assume that this is implied by "start-end".
I agree with you, and I think the documentation is fine. I was just pointing out that specifying an invalid start/end element results in an error and an exit status of 1, but specifying an invalid end-start range results in silence and an exit status of 0, which I think is a bit unexpected.
In any case, I don't think it's a big deal, if it's even an issue at all. I was only bringing it up in case someone thought it made sense to issue an error message there as well.
