In A, the crescendo marking links the intensifying dynamics with the formal structure; it begins together with the beginning of another version of a two-bar phrase (previously appearing in bars 34-35, 36-37, 38-39), this time based on the bar-long dominant chord in D flat/c sharp. In its further development, the music clearly breaks the two-bar pattern and leads with sequences of whole-bar harmonic blocks through an agitated stretto in bar 44 to the triumphant re-appearance of the same dominant chord in bar 45.
The shortened crescendo in GE is certainly due to the engraver's oversight.
The delayed beginning of the crescendo introduced by Chopin in FE (→EE) seems better suited to the natural flow of the music – the signal for dynamic intensification is the movement of the bass and the exhaustion of the two-bar phrase formula applied so far.
