In all honesty, United is most likely to IDB after all the pax on board have filled up the seats and the last few people haven't boarded. However, they will always solicit VDB passengers first. On a short route like SFO-LAX they will always find takers because there are literally a ton of flights between those two cities; not just on UA but also on DL, Virgin, etc. etc.
For that route I would think the chances of IDB are about 0.0001%. I wouldn't even have it cross your mind.

The only way an IDB ought to occur after boarding under the post-Dao rules is not through overbooking but because a seat goes INOP, heat suddenly takes the MTW down and so on. In that situation, the entire aircraft would be offloaded and then all but the IDB would be boarded.
UA only needs to have its IDB order established prior to the flight and available for later DOT inspection.
