Rosberg locked up badly after the first stop because of the front bias, then changed it to a more rear bias based on Hamilton's data, soon after which the problem struck. Luckly Rosberg had more rear brakes left in comparison to Hamilton and nursed the car to the finish.
I'd say Rosberg locked up badly foremost because he was under pressure, braked late and compensated by braking harder, which then caused the lock. After all, he didn't lock them at any point before that instance, when Hamilton was further behind. There's no "right" or "wrong" where brake-bias is concerned - there's always going to be a limit, when you go on the brakes. Usually, you want a bit of forward bias because you don't want the rears to lock when going on the brakes (oversteer with the potential to lose the rear). The ideal set-up would be to have the front lock a bit before the rear would. Also a setting will not be identical on every braking point. I would think that braking from a higher speed causes more weight (load) to shift to the front of the car, so there's no ideal setting for the entirety of a lap. As the fuel load and weight (and grip of the tyres as well as surface conditions changes), so does the optimum setting.
Of course, a too forward brake bias will mean that you are running with less braking power in total since the rear are underbraked (relatively speaking).
