Excellent approach, putting that in my book of tools.

I’d also be sure to ask the second person to finish what they were trying to say after person 1 was done.

There are 2 reasons:

1. Never know if they have a different perspective or other ideas. They may also have thought of something while listening.

2. In the help desk world you learn these kinds of people get worse when they get shut down. If you actively engage them (even if you don’t really want to), they’ll feel heard, and maybe be less likely to feel compelled to interrupt. Plus you come across as a Good Guy® at work.
