Both notations are almost equivalent; however, in exposition Chopin changed the former to the latter, formally less strict yet simpler and thus more explicit, in several dozen bars (see bars 257-263). In the further part of recapitulation, it is also the latter that prevails; hence we consider this place an example of an overlooked proofreading of an analogous place and we include the change introduced in GE in the main text. See also bars 601-603.
