True, there aren't many active 1st Class at one time it seems so this could be someone that they recruited after the disappearance of Sephiroth and Zack. It also always seemed like Prez Shinra / the Turks etc. had no idea about Cloud in the original. Which TBH made sense with the president (who likely wasn't interested) but it was always odd that the Turks didn't know . Unless, I suppose, they didn't know Zack's name and just assumed that Cloud was him (which could apply to nu SOLDIER too, if he's heard "stories" but not names).
