This fact is further explained in the Skanda Puräëa, as quoted by Madhväcärya:

It was actually impossible for Rävaëa to take away Sétä. The form of Sétä taken by Rävaëa was an illusory representation of mother Sétä—maya-sétä. When Sétä was tested in the fire, this mäyä-sétä was burnt, and the real Sétä came out of the fire.
