S.v. πτόλις LSJ notes 'Ep., ... (not Aeol., but an Epicism in Supp.20a.12)' [= Sapph.44.12(13)]', an acknowledgment that an instance of a phenomenon in an Aeolic text does not make that phenomenon Aeolic, any more than standing in a garage makes you a car.
Of course, Sapph.44, the wedding of Hector and Andromache, deals with characters known from epic and is one of the so-called 'abnormal' poems of Sappho, and one regarded as inauthentic (Page, S&A, pp. 65-69, but see Hooker, pp. 39-55)
In relation to p. 69 and Hooker, pp. 87-88, remember that LSJ s.v. πορφύρεος notes 'Aeol. πορφ-ύριος 64 [= 54], Supp.11.2 (πόρφυρον ἄνθος is corrupt in 94 [= 105(c)], and πορφυρ[α] as neut. pl. (–⏑–) is found in Supp.20a.9 [= 44.9(10)]); πορφ-ύριος also in IG5(1).1390.179 (Andania, i B.C.):'.
