Comment (by dd32):

 I believe this would be caused by it being modeled on one of the original
 object caches in use, Memcache.

 https://www.php.net/manual/en/memcached.decrement.php

 > Memcached::decrement() decrements a numeric item's value by the
 specified offset. If the item's value is not numeric, an error will
 result. **If the operation would decrease the value below 0, the new value
 will be 0.** Memcached::decrement() will set the item to the initial_value
 parameter if the key doesn't exist.
