One of the subtle ways he didn't mention is that the words seem to use medium-frequency letters, so they aren't an obvious guess, but it isn't some word with no vowels or a bunch of z's, either. I did notice that after the NYT took over the words now seem to have fewer letters, so it's more necessary to logic out which word it is if you want a good score. Previously I could figure out what most of the letters were with three words, but now I have to work at it. At least until I can come up with well-chosen words for the new regime.
