auctions Expired Uniregistry names go to auction at Dynadot

[Embrand]

Sorry if this is old news, but a search didn't give any results.

So I noticed some expiring domains at auction at Dynadot. But strangely these names were registered at Uniregistry.

Now Dynadot has confirmed to me that they are working with Uniregistry so that expring names at Uniregistry go to auction at Dynadot just like Dynadot's own expired names.

My question is: Why on Earth does Uniregistry not auction off these names at their own platform? It seems pretty strange to me.
