Why was this a blunder?

Played this game earlier. Very enjoyable, however after analysis it seems that there are a couple of things in which I don't see the logic of commented below. I don't understand why sacrificing the Knight or Bishop in this game achieves anything? Thanks in advance.

If you run the analysis as a diamond member, I am sure that it goes far enough to show you what it is thinking:

This is the position reached in the analysis. I only have a Platinum membership.  I would guess that the Diamond analysis goes farther.
 
Basically, both sacrifices have you going after a lonely king. Black's queen is out of play. The king is out and vulnerable to attack.
 
 

This position seems unclear to you?

I didn't calculate it all out, but after 11. Nxg5+ fxg5 12. Qh5+ Kg7 13. Bc4 (or 13. Bxg5) Black is about to be mated at f7, in the style of Damiano's Defense.

Some things to think about. Thanks guys for the comments.

Thanks, I didn't know the analysis was capable of this. I didn't realise it played out an alternative.
