That scenario is pretty much the typical way to have your finisher GCD come up as Demolish has <6s left on the target. If you just do a Demo + Snap rotation, you'll be clipping Demo earlier than that, which would be a DPS loss yes.

The use of ToD or Fracture, or any situation requiring time away from the target can lead to situations where you offset the timing of Demolish, and my analysis has shown me to simply decide whether or not to clip it based on if it has more or less (or equal to) 6 seconds left on the target as the GCD becomes available.

That basically sums it up, if demo has >6 secs left, you are safe to go through another set of forms to refresh it. If it has <6 secs its best to use another skills, namely ToD or fracture, to clip it as least as possible and prevent it from dropping entirely
