To be honest, I don't know. I've grouped my Embrace heals into a macro with Physik or Adloquium (Em on <mo>, Phys/Adlo on <t> so I can choose to use Em manually on same target, diff target or not at all), so when I really do want my Embrace to be used, I pull out Eos on Obey. Anytime I don't need the extra healing I use Selene on fire and forget mode (Sic). She cycles through buffs correctly now and still heals the tank reliably when placed somewhere near them.
I never really paid attention to Embrace recasts, like I said, if I need them spammed on CD, I do so by macro.
