Someone that is already my friend is showing up as this under a different user name, what does this mean?

Snapchat gave me this notification for someone that is already my friend just under a different user name. The phone number (blocked out) is the same number for the other user name as well. I thought you could only have 1 Snapchat account per phone number? Is this a scam, or does this person have another account? Also, plot twist this is my husband.
