This is called inverted market.

Investopedia gives this definition http://www.investopedia.com/terms/i/invertedmarket.asp

he did not talk about the inverted value, take a closer look at the screenshot.

I experience this quite often at bitfinex. But everytime I see this, it is just because the trading engine is not fast enough.
So it was like: someone want to sell 100BTC for 200 , while there are alot orders over 200 in the orderbook. So the 100BTC sell order is clearing all those orders. But this takes some time and for this time you can see, that the bid > ask.

But if your example takes longer than some seconds... I don't know what it could be.
