The ollas use "capillary action" to wick the water from inside that pot, through the wall of the pot, and to the soil.
Water expands when it freezes, thus breaking apart the clay pots from inside the walls.
Ecosystem is everything: a) frequent freeze thaw cycles will be more damaging than few cycles,
b) a dry or almost dry pot, won't get the same expansion pressure as a saturated pot,
c) just digging up the pots won't help - they need to have time to dry before freezing, and stay dry for the freezing weather.
d) and they need to be stored where they won't get broken!
So this is a major issue in some ecosystems. I have tried similar just using a plastic bottle so I'm watering under the soil surface, but plastic solar degrades to fast, so I no longer do that either. Having punky wood in a bed seems to be a good way to help even out wet/dry cycles.
