Covies and Humanity working together is not strange at all.
It happened multiple times throughout the series, for instance in Cole Protocol, Halo 2, Halo 3 and that Bloodlines comicseries.
Working together to fight the Flood happened in H3 (Floodgate for instance), and probably also happened on Delta Halo after Arbiter aligned with the UNSC (but not seen in the game).
Although you would technically say it were the Covenant Separatists forming a bond with the UNSC, and not the "THE" Covenant doing so in this case.
