"Corellon is alternatively male or female, both or neither", this quote gives Corellon agency and control over his gender, which is pretty cool, IMO, as most of us do not have such control. However, describing him as androgynous and/or hermaphroditic/intersex gives him more identity, as it becomes part of who he is, rather than something he can change at will. But, it's all shades of meaning that don't stray too far away from each other.
In my campaign, humans ask their elven friends, "Your god, Corellon, is he a man or a woman?" And then they are mystified when the elves respond, "Yes."
Okay, I like this way of describing Corellon better. Well done. I'll use this.
