Sorry. I believe you may be correct. It seems to match up.

Part from my `man top`
---
        o: VIRT  --  Virtual Image (kb)
           The total amount of virtual memory used by the  task. 
  It  			  includes
           all  code,  data  and  shared  libraries  plus  pages that 	 
 
           	  have been
           swapped out.

           VIRT = SWAP + RES.
