It sounds like he's sensing something with your wife.
You say you've "got her to be" the sole feeder, etc. Does she want to be, or even enjoy it? If not, she may very well be sending non-verbal signals to the dog.
"Telling him off" does nothing, so don't bother with that.
I recommend getting the Dog decoder app. It will help you read the dog's non-verbal communication so you can figure out what he is feeling when he does it. Why he's doing it will determine how to counter it.
I always suggest people just talk to the dog as they go about their day. Just voice thought out loud and direct them to the dog. Like "Joey, what shall we have for dinner tonight?" or "I guess it's time to do the laundry, what do you think Joey?". Often, that helps the dog relate to the person better.
