That's a load of horsesh!t. The property is no more abandoned than a wallet dropped on the street or a bicycle left unlocked in public.
Whether someone abandoned property is based on the test of whether they intentionally gave up ownership. In the wallet example, the property was lost. In the bike example, the owner clearly had no intention of giving up ownership.
When you leave your property behind after being evicted, you are intentionally giving up ownership if you had a chance to remove it pre-eviction.
