How do you know both flights are oversold? And the term should be overbooked...it's not oversold until more people show up to board the flight then there are seats for. There are lots of flights thus are overbooked, but don't end up being oversold.

And IIRC, I thought UA generally doesn't overbook the front cabin.

Seat map isn't a reliable indicator, if that's how you can to your conclusion. It's very possible there are a couple of seats that are blocked for selection, and will be opened up at check in time.
