Can this be considered an insult?

I went for my sister’s house a day after her wedding and her husband introduced me to the members of his family but when he introduced me to his youngest brother who was a year older than me, he made this remark “when my brother said his in-law was here I didn’t know he was talking about you”. The first time he saw me was at the wedding and we didn’t even greet each other let alone speak. Was this an insult?
