I'm saying that after 500 years Heinrich wouldn't just show up and decides to kills some angels. He was barely able to manifest himself for long even after the seal was broken, nevermind the fact he wasn't in his beserker form. Not only that but he just kinda..teleported there. With no apparent reasons.

Like I said, he is just kinda teleported there with no reasons, like any other creatures that were summoned through dimensions. Also, pretty sure the reality were Heinrich completely fused with the Angel Halo wouldn't be possible in the same reality where the sword is still just a sword.
