The only digit written in FEH (by Chopin?) determines hand position for the entire 1st group of semiquavers; in this situation, it seems natural to repeat this scheme in the next two groups, where the digit determines fingering of the entire bar. It coincides with Fontana's fingering in EE, which is described in more detail.
