Computer beats human at Shogi

One of the comments on that article says the Shogi situation depicted in the article's photo cannot happen. Can any Shogi players here confirm that?

If not an illegal position, then a ridiculous one. The king is in check from two opposing pieces attacking on opposite sides of the king. Just as in chess, double check can happen only if the piece moved reveals a discovered check from another piece. But that cannot be the case here where both checking pieces are adjacent. Technically, it could be argued that the object of shogi is not checkmate but to capture the opposing king. A king left in check is immediately captured. So the king was not captured here? Ridiculous.
