Hey Dennis I have grow a number of Ipomea with most of them being the native species. I. pandurata is one of my most favorites and is like a "native" moon flower. I have seen "twin" embryo occurrences happen before with Ipomea as well as other plants, but never commonly and it is certainly not typical for I. pandurata which is usually single. I am not sure I have seen this with I. pandurata itself, but I know I had some I. trichocarpa and I. macrorhiza were there were several twins in a batch of seedlings like yours. Because of the root system of this species it would be curious to see how they develop.
