Don't get me wrong; I don't necessarily believe that freezing is something to be taken lightly; I'm just parsing the sentence in NFPA 13. And you're right; there's a revision bar in my 2007 edition next to 8.16.4.1.3.
I'm not so naïve to think that this wasn't interpreted that way by most AHJ's in the past when the code technically didn't require heat from 32.1dF to 39.9dF. It looks like the committee cleaned this up, finally. Thanks! Eric J.
