Steam is being used as the heating medium - it will be undesirable in the flask as it will change the partial pressure of the mixture and will be carried over in the condensate.

steam is used to raise the temperature of the mixture. If it was generated inside the mixture, water would be mixed with the substance to be distilled.

heat = steam = evaporation and distillation.......
If the heat is generated by boiling, then the
steam will cling to the flask and become
water vapour instead, depending on what
liquid you are using and in which lab conditions....
