In FE (→EE), the minims are written in such a way that it is impossible to extend them with a dot. One can assume that the notation resulted from the minims having been added to an earlier notation of quavers only, perhaps still in [A]. Anyway, later proofreading of similar figures in exposition (cf. bars 257-263) and the notation of bars 605-606, 608, 610 and 613-618 prove that Chopin opted for a notation using one notehead, whereas the discussed bars remained uncorrected, probably due to inadvertence (it also applies to bars 607, 609 and 619-620). In the main text, we do not add a dot extending the minim in bar 602 due to the repeated bass note at the end of the bar (cf. bar 245 and 267-270). However, it is impossible to determine whether Chopin would have actually differentiated the notation of this bar with respect to the adjacent ones.
