Chopin changed the hairpins' concept in A: he deleted the crescendo hairpins in bar 9 and he prolonged the ones beginning in bar 8. Probably both changes were introduced at the same time: Chopin deleted the short hairpins in bar 9, planning to introduce a longer crescendo indication. In order to do that, he added an extension of the hairpins' arm from bar 8 or even the entire hairpins in two moves (the too short sign and extension).
