Why do people think these words are synonymous?
Look them up: humbled vs. honored
Funny, to me they seem to be kind of… um… opposites. And yet…
The response has far surpassed our expectations and we are extremely humbled by the huge interest.
That quote seems typical lately of the kind of stuff I see by developers of exciting software, by bloggers who’ve been dugg, whatever. The obsessive word nerd in me is slightly irked. 
Fortunately for you, I have the attention span of a gnat, and I’ll get over it momentarily.
In that context one can be both.
It’s not the best locution, but the intent (and it’s not outside the customary usage of the word) is that such an honor reminds the honoree of just how little they may have done (if only in their mind’s eye) to deserve it.

You are right! Boy, this bugs me so much that I googled the phrase humbled vs honored to see if anyone at all has the same objection.
Christians ought to get it right, “customary usage” aside. Read the Bible to get a clue how nice it is BE humbled. Our aim is to humble ourselves and avoid deserving to be humbled.
