From : Calendar Clues: Pope Francis and the Lex Orandi of Papal Maximalism
The alterations to the quasi-octave of 22 July-29 July are twofold: Magdalene is now a feast, and Martha’s day is now Mary, Martha, and Lazarus. The latter change follows what had become the practice of the monastic rite. It makes an implicit declaration that Magdalene and Mary of Bethany are not the same woman; this had been asserted in the unofficial commentary that accompanied the 1969 calendar. The traditional liturgy for 22 July is a composite liturgy: there are allusions to Magdalene; to Mary of Bethany; and to the anonymous peccatrix of Luke’s gospel. No woman is omitted; no rigorous delineation of identities is imposed on the lex orandi.
As far as I'm concerned, for the Roman rite to be aligned with the East in recognizing that the three women were distinct individuals and not one in the same, is correct.
