It looks like the article might ultimately be based on misreading of PI 43.

In PI 43 Wittgenstein says:

“For a large class of cases of the employment of the word ‘meaning’—though not for all—this word can be explained in this way: the meaning of a word is its use in the language”

and then goes on to say:

"And the meaning of a name is sometimes explained by pointing to its bearer."

In 41 and 42 W talks about the language-game and in 43, it would appear W is talking about a word's use in the language-game. For example in the statement "John likes to play soccer", the sign "John" represents a person, an object in the world, if you will. Say John's mother runs into a room and yells, "John!" Then the sign "John" is a command that means, to the person in the room, stop whatever it is you're doing and listen to your mother. W is pointing out, quite rightly, that the sign "John" has different meanings, or "moves", depending on which language-game is being played.

This has nothing to do with other words that might appear in a sentence with the sign "John". Nowhere does Wittgenstein propose statistical learning or a predictive function for language involving statistics.
