The article claims you can't set the combination word, so probably assumes it is always a valid dictionary word preset by the manufacturer. That said, the WordLock web site says you can change the combination, and obviously you can on similar locks that have numbers instead of letters, so really the author probably just didn't know how.
I know about this limitation, and I suspect it is only true for some "low-end" models of the WordLock.
I have one and it is configurable. For a while I used ROOT as the code, ha!
I have seen ones which are immutable. They featured thinner cables and smaller locks. (Maybe there are more hefty WordLocks which are also not configurable; I don't know.)
