"Without a neutral connection at the load, all of the current "out" of the top source must flow "into" the bottom source. Do you agree?"

No. That is a very simple way to describe it. Thats not how it works. Use this example:
You have a 120/208 volt service from the utility. There are 3 phases A,B and C.
The angle betweem the phases is 120 degrees.
120 between A&B, 120 between A&C and 120 between B&C. Take 2 conductors and connect one to A and one to B. Connect these conductors to a 208 volt load. Has the angle between A and B changed. No. Its still 120 degrees and the voltage is 208 volts. Go to the site below and it will show you how the Sine waves look for the 3 phase service. The net voltage between conductors is the net value of adding the
voltage levels on A and B. This is the real way it works.
