Adverts remaining up on CL often means nothing.
We've discussed this before; sellers leave ads up on CL often long after something is gone. That or they for reasons unknown update the thing to say "sold". Large numbers simply leave an advert up until it expires and CL thus removes.
Seller left advert up for the AEG washer one was after for several weeks after it was gone. The ad is or was still up long after TD collected that vintage Jamesway dishwasher... and so it goes.
