Maybe, that does appear sound, but my comment about Taro not recognizing him comes from the fact that Taro fought in the Dark Spark War and presumably saw all the different Ultras from across the multiverse. Given that there are one million members in the Space Garrison, his comment and the way he said implies he is confident in his memory that he would everyone of those numerous Ultras. Given their advance nature, it is not unlikely to assume that Ultras have perfect memories.
