If the domain was registered with GoDaddy or WWD it will take 42 days before it goes into registry redemption and then it will take another 30 days or so for the GD backorder, Snapnames, or any other drop catching service to be of any value. As a side note, keep in mind that GoDaddy backorders placed before a domain is at auction or during the auction (if there are no bids on it) will place a bid on the domain. If no one bids beyond the $10 starting bid then the backorder will capture it on the 43 day.
As far as the difference between a GD backorder and WWD backorder, it depends which registry connection captures it as to whether it goes to the private GD auction. If the WWD backorder had caught it then it wouldnt have gone to auction.
Theres more detail and confusion when it comes to the new GD system, but thats the rough reality on backorders from GD.
