The indication sempre legatiss. was added in a proofreading of FE (→GE,EE). It could be assumed that Chopin added it instead of a slur in bars 85-88, overlooked in FE. A similar addition in bar 81 suggests, however, that the composer did not see anything wrong with simultaneous presence of both indications. Therefore, in the main text we give both the slur and the verbal indication.
