I believe that it would, but I'm not positive. There aren't many situations where you'd really need it. But one that I can think of is during Garuda fight, toward the end you could cast surecast then pre-cast medica to get party back up to full health quicker after the big aoe hit that interrupts casts. As we see more high level content, I'm sure there will be more situations to use it. You could use swiftcast in teh same scanario, but I prefer to always save swiftcast to be used as an instant Brez with a 1-min CD.
Either way if you go deep enough into THM to get swiftcast, then you already have surecast, might as well use it![]()
