The staccato dots, present only in the 2nd and 4th bars of this four-bar section, is probably a result of an inaccuracy of Chopin or of the engraver. In the analogous phrase of the exposition (bars 61-64), the articulation is marked much more accurately, so it seems that Chopin wanted to mark all bass notes in the same manner. According to us, the presence of dots in FE (→EE) in bars 190 and 192 indicate that Chopin imagined all bass notes in the recapitulation to be performed staccato too.
