And there was a perhaps small, but certainly non-trivial stream of people asking how to change that because their system(s) were indeed multiple ports connected to the same broadcast domain.
Long since then Sun changed their defaults, and we've gotten things like bonding, so I think any assumption that a system with multiple ports will not have then connected to the same broadcast domain is brittle at best.
