In A the arms of the 
hairpin differ by a half of a bar. We assume that it is the bottom, longer arm that is reliable, reaching the topmost note of the three-bar quaver sequence. In GE (→FE,EE,IE) the mark was led only to the end of bar 330, in accordance with the range of the top arm; moreover, the beginning of the mark was shifted by almost an entire bar, making it look like the hairpin that was printed in an analogous phrase 4 bars earlier.
