My understanding (I don't do world PVP so may be off on the details!),
is that, so long as the other player is at least a green level to you
then it should be an honorable kill. Grey level will not give
honorable kills, all others should.
Of course, I assumed the default UI actually showed level range
colours, I'm sure it used to, but can I see it now? No lol... perhaps
I'm thinking of healthbars, which may or may not show it, depending on
your settings. https://wowpedia.fandom.com/wiki/Mob_difficulty_colors
may help; if it's accurate, then if you are lvl 60, anything 51 and
below will be grey to you, and so likely not count.
I think if you're camping 1 player repeatedly for multiple kills,
there'll be a cooldown of some minutes, as well, so it may count once,
but then not for, say, 5 or 10 minutes afterwards.
