Pfah! Cannot they write problems like this without ambiguities? We hates them, we do.

The one that's bothering me is the "can" in: "If and only if at a particular point no word at all from the dictionary can be inserted,". Does that mean "can be inserted to successfully produce a solution"? Or "can be inserted whether or not a correct solution results"? If the former, given the single-word dictionary "aaa", "55555" has solution "5 aaa 5". If the latter, it has no solutions.
