A might be any internet host, so (generally) we must assume intermediate
routers.
    
H---|
I---|---G---........---A
J---|       Internet
K---|
    ^ Subnet N (with hosts H, I, J, K, G)

Sure. But the original question was, looking from H's perspective, how
often in the real world one will find further "gateways" (say F) for
incoming traffic (to H).

H---|---F---.......
I---|---G---........---A
J---|       Internet
K---|

My only influence is on H.
