Yes, so that should mean for every element one tests to see if the node.prefix or any of the attributes prefixes are the same as the namespace prefix avaible in its axis. I haven't dug deeply but in the small tests I can do, this is a neglible difference in performance (and for other reasons, exc-c14n tends to be slight faster as the size of the document grows.) However, I'll also say I'm not expert at this...
