That depends on the registry's policy and also on the status of the domain prior to deletion.
For example in .pl registry it's not practised to reserve domains and definitely not handing them over to a selected registrar, unless the domain was deleted as a result of a lost domain dispute.
That said, I cannot tell anything about your specific case and I don't even know if you interpret it correctly.
Thank you for the response.
I've got another post started with NameCheap and trying to understand the validity of their expired auctions for domains where NameCheap isn't the registrar for the domains being auctioned. Still trying to figure that out, or get a reply from someone that knows.
In the process of looking into that, there was an .xyz domain being auctioned at Namecheap (edit: that wasn't registered with Namecheap) that I was interested in. I didn't bid on it.
Someone else did bid on it, and then won. So I was interested to follow this. The domain whois info and RDAP querey responses didn't change and remained in dual pending delete status. I also set up multiple backorders with 3 different companies for the domain I was interested in.
I've also written some scripts, along with modifying some others, to grab RDAP queries and also make API calls.
I grabbed RDAP query responses up to the point when the domain dropped. I also had API calls going to attempt to register the domain.
I was expecting my API calls to be too slow, but I didn't expect the 3 backorders to fail. All failed. I checked the RDAP query responses and at the moment of drop, the domain status changed to: "This domain has been reserved by the registry, and is not available for registration." I've seen this happen before when the registry claws back domains to turn them around as new premium priced domains. However, after roughly 5 minutes of this status, the domain was then registered with Namecheap.
I'm assuming the person that bid and won the domain auction, was awarded the domain.
I've never seen this before though, where the domain is counted all the way down to drop and then not actually dropped, but passed off by the registry.
Again - I'm new to a lot of this. Maybe it's always been this way. That's what I'm trying to find out.
In regards to the other post I have about Namecheap and the auctions - I still don't know that yet. I'm going to try and follow through with some other tlds and see what they do.
From this example, to me, it looks like the registrar Namecheap may have a deal in place with the XYZ registry to final auction domains that are in the final stages of "pending delete" status. (Maybe?)
