Steam distillation quest

From my reading there are 3 types of steam distillations.

1. Water distillation (Hydro distillation) wherein the water is mixed with the starting material in the boiling container.

2. direct steam distillation, the starting material is suspended above the water in the boiling flask, supported by a metal mesh or perforated screen

3. dry steam distillation, the steam from a boiler is forced to flow through the starting material in a separate container. the latter variant allows the steam to be heated above the boiling point of water (thus becoming superheated steam), for more efficient extraction



Questions are, in direct steam distillation, is it likely for volatile liquid to end up in the boiling vessel? (I'm guessing no)

And, lastly, what are the benefits of direct steam distillation over water distillation?

I think I've got it and incase anyone else is wondering, pm me.
