Spells: Blanket of Forgetfulness weirdness?

[Freakish]

Last patch they made it so that invisibility would not clear aggro upon a successful FD. Perhaps it has something to do with this? Both are mem-blur mechanics.

I was doing queen bee in sky one night recently, raid wipes / camps out as final bee spawns. I'm sitting far away invis when someone kites it over me, it ae's and I instantly re-invis with CoS, con it and I appear to have no aggro (Indifferent). I drop invis after queen bee resets and she makes a beeline (lol) to me and gives me the touch of death. She did not go anywhere near me until I dropped my invis.

I am not trying to hijack the thread, but simply pointing out other instances in which /con did not actually prove there was no aggro.
