It's not misleading, as I have already said, the royal He is with a capital but that's not the only point, the main point, which you seem to have ignored is that he or the masculine in general, is dominant in english. My example from before, "mankind". It refers to the whole of humanity, not just men. If you want to discuss this point further, it would not be a theological discussion but a literary one.
And referring to something as royal does not anthropomorphise it. I think you have a loose understanding of the term or in your own opinion, royalty is only for humans but the angels revere Allah more than any one or anything else, as do the trees, the animals, the mountains and so on. All creation is in reverence to Allah. Reverence and the idea of royalty may be human to you but in the theological sense it is not.
