That's what I imagine. Wife cooking and cradling the baby with one hand while the other types on the computer. Husband in armchair smoking a pipe while reading newspaper.
Why? Has your workmate said anything about sitting in an armchair smoking a pipe while reading a newspaper? Have you observed him doing that?
If your workmate is taking a year of paternity leave and his wife is working from home, my assumption is that he'd be the primary caregiver for diapers, holding the baby, putting him down for naps, cleaning up around the house, and his wife would be nursing the baby and possibly sleeping with it (which is basically a full-time job itself in the newborn phase). That was roughly how we divided responsibilities when I was on paternity leave.
