Is this disrespectful?

I work with my husband. He has been sick for the past couple of days. I had a coworker come say good morning and ask how he was doing. He was back and I said he was okay and back at work. My husband jumps in and says my wife doesn’t speak for me. But I’m here.

I was thrown of a bit by this and told him as such. His response was that he was joking with me. I didn’t find it all that funny. More on the line of disrespectful? I don't know
