I mean Havok is Cable's uncle, as well as a well renowned leader in the X-Men community, plus a different timeline could mean a different history with them being closer. Havok was part of the new X-Men team with Storm that formed around the classic Giant Size issue, so there's at least historical significance there. It's not too much of a stretch where suspension of disbelief is an issue.
