I don’t think the separated soul necessarily knows all individual things in heaven and earth, but instead knows to the extent established by Divine order. St. Thomas describes this example as well in his Summa, giving his explanation of how the operation of the intellect necessarily changes after the soul separates from the body. Summa Theologica I, questions 75-102 is where he describes the nature of man and his soul, q. 89 is where he speaks of knowledge in the separated human soul. It is only later in his Summa, IIb q. 171-178 where he speaks of “Gratuitous Graces” Divinely bestowed to certain men and women (e.g. prophets), and q. 173 is where he describes his understanding of how the intellect works when it receives such Divinely imparted knowledge. He concludes that some but not all Divinely bestowed knowledge requires “abstraction” from sense-image, but goes on to state that for all such knowledge, “the perfect judgment of the intellect is effected by its turning to sensible objects, which are the first principles of our knowledge, as stated in I, 84, 6.” In other words, St. Thomas explicitly joins his understanding of Divinely bestowed knowledge (IIb, 173) with his previously asserted understanding of the nature of man and his soul (I, 84). In this earthly life, sense-image is used no matter how the knowledge was gained, sometimes through abstraction, but always during the intellectual judgment of the knowledge received.
