Great question. The highest voltage source will assume most if not all the total downstream load. The design goal for use of diodes in this manner is not to spread and share the load between two sources but to insure that the loads are supplied with energy irrespective of the condition for either source. I'm working an accident case where a couple of systems were combined downstream of a pair of diodes without modifying upstream protection to accommodate the SUM OF BOTH LOADS on EITHER energy source. This was but one design error that stacked on top of several others to bring an airplane full of folks to an unplanned arrival with the earth. The little things DO matter.
