Permanent light usually does not have the same intensity as a flash. For a flash, capacitors store a LOT of energy to release in a very short period of time, then they need to recharge. Permanent light would require extremely high wattage to compare, which is a dramatic increase in cost.
For a picture like this, you want exposure time to be really low, to get a crisp image of the fluid dynamics. Think 1/1000 of a second. The amount of light a flash pushes out is so dramatically more than constant light usually offers, and no flash recharges fast enough for a burst of shots like that.
Beyond that, you can also see their softbox with the flash above the subject. So I feel confident in my assumptions.
