What is the difference between dash (-) and zero (0) in the bidders number?

I was looking at some names and noticed this difference. Can anyone tell me what it means? I can't figure it out.

Domain marked by "-" will be deleted soon, Snapnames will try(may be) register it.
Domain marked by digit not will be deleted, it's expired domain, which were renewed by Snapnames partner registrar and will be on Snapnames auction soon or domain placed by Snapnames customers. Digit show how many customers placed their bids for domain before auction start
