   Right. GR's treatment of the event horizon is more "the region inside   
   which the light-cone of a particle can only describe a world-line that   
   cannot escape the region". Spacetime is twisted enough that once inside   
   there is no way out. The particle that is directly in between the two   
   holes in the merged event horizon will end up inside one of them, no   
   matter what. There's simply no other direction to go.   
      
   Black holes are not amenable to Newtonian analogies, except when treated   
   as a point mass interacted with only from a distance and speed where the   
   interactions aren't getting all relativitied up.
