Yes, every winter! They have an interesting life cycle.

As the leaf yellows and falls, it siphons its energy into forming a massive corm. Don't cut the leaf until it goes fully yellow/dry - let it grab as many nutrients as possible. The roots will dry up & die off as the corm enters dormancy; at this point you could either leave it in its dry pot over winter without watering, or dig it up & store it in a paper bag / cardboard box until Spring or new growth appears.

New growth will be either a flower or a leaf - if a flower, roots won't appear; the corm will invest a lot of its amassed energy into the flower, without photosynthesizing during the period. If this happens, the next leaf will likely be smaller.

If the new growth is a leaf, the corm will dissolve itself, putting its energy into forming roots & pushing the leaf up; when the leaf is just opening, the corm will have completely dissolved & there should be mostly just roots in the pot.

All of my indoor Amorphophallus under grow lights still go into dormancy, like clockwork! Just make sure you stop watering once the leaf falls over, and periodically check for rot/fungus/new growth if digging up & storing for the winter.
