Omission of this 'one' in GE1 (→FE→EE) probably resulted from it having been considered a consequence of an accidental quill movement.
One can ponder why Chopin indicated fingering only in the fifth similarly structured passage. It could have been related to tucking the thumb under on a black key in a situation when the previous passage included white keys only (in bar 472 the position of the thumb on the black key was forced already in the previous bar).
