I think this is some interesting insight into clock management situations that don't make sense on the surface. Before the half, the Pats had a 1st down and could have clocked it rather than let 15 seconds run off the clock, take a shot at the endzone (nearly worked!), and then only leave enough time for a FG with 6 seconds to go and a TO on the board still.
Sort of like the end of the Super Bowl where it was a little hard to see why they wouldn't take a timeout at the goalline, the answer came down to they thought they had a better chance not giving everyone on both teams a time to reset. But also that things were happening quickly and they could've done better perhaps.
