In A the 
hairpins clearly refer to short melodic connecting passages leading to the Neapolitan chord. In FE the marks were extended and their reference to the part of the R.H. is unsure. According to us, it is a result of the engraver's misunderstanding of the manuscript. In EE and subsequent GE,s, the mark in bar 48 was extended after bar 47.
