Prophecy didn't mention breaking the barrier. It said "they will return, and the underground will go empty". Of course, it can refer to Asriel setting monsters free in True Pacifist ending... just as well as it can refer to Chara killing everyone in Genocide. If we assume that Asriel's form after absorbing Chara's SOUL was more or less the same as his final boss form, Delta Rune can also symbolize either of them.
