It is just one example where the connection between options in Part 3 is based on common synonyms (or even, sometimes, on a common word in an example of the word's usage). It seems to be built into the way the game selects matches (whatever that is), because it has been there from the start. Perhaps the hint (which I must say I haven't even read in years) could be reworded to indicate the possibility of that kind of connection.
