It didn't have to be the case — it could have been that these planets were very, very hot on the dayside and very cold on the nightside, but apparently there are these very strong winds that can move energy around to the cold side, so the nightside on those planets is really quite hot.
Assuming Proxima b is tidally locked, Webb could then detect changes in the planet's thermal glow as its cold, nightside and warm, sunlit dayside shift in and out of view across one complete orbit, rather like watching phases of the moon as it circles Earth.
