Yes, it is. Each SCOTUS Justice is responsible for at least 1 of 13 circuit courts of appeals. Roberts has DC, Federal, and the 4th Circuit. It isn't interfering either - it is their job. They will decide on issues exactly like this emergency stay, or stays of execution, injunctions, or anything before that court that can be decided by a single judge. Wikipedia has a good blurb on Justices as circuit justices. Anything more in-depth you can search for.
By the way - this isn't anything new. This situation has been posted in here before, and recently. I don't recall off the top of my head what the issue was (something dealing with Trump and the raid I believe) but the consensus was that it would be ok because Justice Thomas is responsible for the 11th Circuit Court of Appeals (part of which is the Southern District of FL).
