Short sale but lien appears to be well below list price

[Tom Rottler]

Looking for some insights here, old google didn't have them. I found a listing for a short sale that meets my investor parameters. I also found the foreclosure proceedings in the county clerk of court filings. It appears that the lien amount is approx $153k from the original 2008 loan but the listing amount is >$200k. That doesn't seem underwater so not sure why it is listed as a short. There doesn't appear to be any refinances in the public record. Their agent has shared that list price is the bank approved price and won't go lower. Any thoughts on why a seller or sellers agent would list as a short if it isn't underwater?
