Yes, but one can easily stop, and then dismount.
In any case, opting for an off the saddle dismount would not have changed anything in this case.
Either way requires committing to one side, leaning that way and planting the foot with the other foot staying on the pedal, either for control, or for support off the saddle.
In fact, I'd venture that changing sides would be harder once your off the saddle and supporting yourself on the "up" foot.
