I'm surprised too. This algorithm is about understanding language, and surely that includes understanding the intended usage. This is something humans have to do all the time. So what if there isn't a formally archived consensus on the definition of "landed" as used in the example. The intended meaning is clear, and so hats off to the algorithm for rolling with it, that is in my mind the fundamental goal of understanding language.
It's more or less impressive depending on whether the algorithm already ate a dictionary; then it's the difference between inferring from context, as people do, and simply knowing all of the known unconventional usages in a very inhuman way.
