It might be different on an Intel 8088. What I saw was two bytes loaded from the bus (at the address that was left in the IND register) placed in ES or DS, and the offset part was loaded from a second hidden register that contained the previous word read from or written to the bus (excluding instruction fetches).

Glad the sniffer logs were useful! I have been using them pretty regularly for debugging and profiling things.
