I'm not seeing how this could work without the points. It's entirely dependent on the points still, to provide the timing signal.
The Bosch ignition controller is just used (as far as I know) to do two things in the later model cars - take a light weight 'logic level' signal from the ignition computer and turn it into a more powerful on off current for the coil, and to (in certain control module versions) control dwell. But when you're using point and a condenser, you already have the amperage capacity required to run a coil, and dwell control of properly adjusted points is entirely adequate for the job.
I think the first picture, using the GM module, there is some advantage, I think that module steps up the voltage going to the coil somewhat, like an MSD box, although on second glance at the wirting diagram I don't think that's happening.
I guess in either case, you do reduce the current loading of the ignition points, so they should last longer, assuming the fiber block that rides on the cam doesn't wear out.
The main advantage of the Crane and Pertronix points replacements are that the points and condenser are completely gone, replaced by sensors that are a lot more immune to slight distributor shaft wobbles that can happen when the distributor is well worn.
