Don't remove good sentences just because they don't follow the rule! I just wanted to know why it meant that; if it's a bit irregular, then it's it's a bit irregular. But if people say it, then it's still worth knowing.
I still don't understand, however, how you tell when как mean 'how' and when it indicates perception of action: is it just context? How would you say 'They see that you live'? (They, perhaps, tried to kill you, but now you've escaped, and they've noticed it.) Or is 'to live' not a verb of action, but just a state? In which case, it all makes sense.
