^That may have been the case in the beginning, but in later years Leland Chee & co. became obsessed with working each and every aspect of the Marvel comics into the modern EU continuity, even when it didn't fit.
Wookieepedia's article on the Legends Boba Fett even lists both of his escapes from the sarlacc occurring in the same continuity.

Of course, I realize this could just be the case of the Wookieepedians being stupid with their inclusivism, not Chee & co.
