confusing suggestions of moves from the engine at chess.com

I'm new to chess and to this site. Sometimes when I review a game I get a suggested move like the following, which I simply can't understand. It says best move for me is horsie to h6.

It seems to me villain has three pieces to move into h6 and I only have my bishop to support. Am I missing something?
I played as white. 
EDIT: I had posted the wrong image, now it's corrected!

Simply the standard suggestions when you press analyze a game and go through the game, it shows green arrows with the supposedly 'best move'

And WOW to the fact that I missed that possibility.

What side are you?

Update: I have now corrected the post, after I had uploaded the wrong image at first.

That is correct 0mek.
Thanks for the answer, I had not considered that. Makes sense! 

Makes sense now 0mek, took me a while to understand, as I had to google names of the pieces and meaning of x in the notation. 

Also what I see here is that you got out just your knights and your queen and went attacking.

It would be better to develop your peices and castle before you attack

Also Bishop and knights are a very strong attacking force so before you go into attack make sure the bishop and knight are in sync with each other.

Hope that helped.

b4 doesn’t protect your pinned knight. Black can take the b4 pawn for free with the black queen.

Your f rank knight has no safe squares to retreat to and is under attack from the rook (the black rook could take your knight and then it would threaten your queen).

So your f rank knight has only one option, a “desperado”. A desperado move is when you take the highest value piece you can (with the threatened piece) before it falls. Here the engine is saying to take the h pawn with the knight before loosing it.
