There are basses, and there are Thunderbirds!
For those new to the three point bridge - the intonation screws and saddles basically rest in slots in the bridge. If you remove the strings and flip the bass over for some reason they will fall out. Good news is, it only takes about a second to put them back in (just be sure to put the correct saddle in the correct slot since they are matched to the neck radius). The saddles will not fall out with the strings removed as long as you don't flip the bass over, so it's really a non issue.
My biggest beef with the bridge is that ideally you should remove some tension on the strings if you intend to raise or lower the bridge to adjust the action. Of course that means you have to tune to pitch to check for fret buzz then detune to adjust the bridge, then retune to see if you have it right, then detune and make more adjustments, then retune to check again, and so on. If you decide that's too much work and try to adjust the bridge under tension you run the risk of pulling a threaded insert out of the body or having the screwdriver slip off the screw head and damaging the body. Other than that, I really like the three point.
