If I read it correctly, thunder 1 has no chance of clipping no matter rng. Also, it has a lesser cast time making it more likely to go off before needing to move if targeted, but that's my own interpretation of a benefit of that rotation. And, as it was said before, it allows flexibility in returning to the fire rotation, leaving the least downtime from casting no matter when the mana tick is, possibly returning straight to fire when thunder is cast if the tick comes immediately, or giving a spell to occupy the downtime if necessary to wait.
