Freckles is an evergreen Group 1 (no pruning needed) and The President is a deciduous Group 2 (prune back to a pair of buds in early spring) so you will be able to tell which is which as the large flowered one will have no leaves when it is time to prune. However, my experience with Freckles is that it is a bit of a thug and may swamp the other one, making it difficult to see the stems of The President so making pruning a real hassle. You can prune Group 1 types to try and keep them under control though.
However, I think the main issue is that the pot is probably too small for both and even just one of them may struggle. If you want an evergreen feature then plant Freckles otherwise The President, but I wouldn't risk both.
