In the main text we give the version of GE, which is probably later. In AF one can see that the hairpin blends with the L.H. slur, which could have prompted Chopin to use a verbal indication in [AG]. In FE the hairpin breaks at the end of the line, in b. 74, which EE reproduced in the simplest way possible by inserting a complete mark of such a range.
