Why is it terrible to cutoff water at the street, assuming he also opened all the faucets long enough to drain the lines?

If you do be sure and open all of the faucets , but you are still taking a chance because you will not be able to drain all the water out of The lines unless you blow the lines with an air compressor, so you will still have water in some of your lines, as long as when it freezes the ice has somewhere to go (hence leaving all the faucets open) ice will form along the line of least resistance and go long ways inside the pipe and it not burst, BUT if you have an ice plug form and trap water in a dead space then that water freezes it will burst a pipe, same for dead end connections that you forgot to leave open, toilet fill lines, ice makers, washing machines, dishwashers All of that takes prolonged super cold temps , but best to just leave hot and cold dripping, set a delay start on dishwasher, empty your ice bin and possibly put a pencil under the flapper inside the toilet tank , all of this is overkill for most modern slab houses, I have a 70 year old camp on pier and beam in S.W. MS, I will be doing all of the above, a $100 water bill is much better than a several thousand dollar plumber bill on Christmas Day Good luck
