The only explanation I have to that is namejet must be auctioning the same domain twice. Once as a pre-release domain during redemption period and then if nobody has taken it, a few days later as a pending delete domain.
I took 1000 random pending delete domains from namejet and tested their registrar. I found 82 enom domains. Also I found lots of godaddy and moniker domains.
The system works like this:
Godaddy auctions godaddy domains during redemption period. Snapnames auctions moniker domains during redemption period. And namejet does the same for enom domains. During that stage the other dropcatchers don't see each other's exclusive domains. In other words those domains are listed only on their partner dropcatcher. You can take a pre-release namejet domain and try to find it at snapnames. You can't. Then if those domains are not taken they enter pending delete status and the same domains are auctioned again but this time all dropcatchers will list them.
A few years ago snapnames was using the terms partner registrar and other registrar. I like that a lot since it was very easy to understand. Later on they started calling partner registrars as "expiring domains" and other registrars as "deleting domains". I think this new terminology is totally crap and they should revert back to the original.
This is why you can see godaddy and moniker domains at namejet under pending delete section. You can also see enom domains on namejet under pending delete.
The domain you bought at namejet must have been auctioned at namejet a few days prior to that auction and nobody took it.
On namejet, under "my account/ reports" I can see all domains I won along with their source. The source is either pre-release (just another name for partner registrar) or pending delete. I checked all pre-release domains and all of them maintained their original creation date. None was reset. So I think you will see that the domain you won has was a pending delete domain.
Let me put it this way: Most pending delete domains are unwanted waste that have already passed one auction. If any moniker, enom, godaddy, network solutions, register.com, dotster directi domain enters pending delete status it must have been already auctioned once and nobody took it. If you want good quality domains you need to find them on their partner dropcatcher before they enter pending delete status, while they are still in redemption period.
Therefore name.com has no chance catching a quality domain that is registered with one of the major registrars unless the domain was overlooked during the first auction on its partner auction house. On the other hand if the domain is registered with one of the smaller registrar then all dropcatchers including name.com will genuinely try to catch it.
For those who got confused with the terms. This is what different sites like to call the same thing:
1. pre-release (namejet.com) = partner registrar (old snapnames.com) = expiring (snapnames.com) = exclusive (namecatch.com) = exclusive (dropday.com)
2. pending delete(namejet.com) = other registrar (old snapnames.com) = deleting (snapnames.com) = other (namecatch.com) = unexclusive (dropday.com)
