DOMString and sequence are distinguishable, yes.

As for how you decide which overload is being called, that's described at
http://dev.w3.org/2006/webapi/WebIDL/#dfn-overload-resolution-algorithm

In this case, step 13 is reached with i == 0.  The substeps of step 13 are
followed, you skip step 7 because V is not an object, and then step 8 treats it
as a DOMString.

That's assuming what's passed in is a primitive string.  If a JS String object
is passed in, it will in fact be treated as a sequence the way the spec is
currently written, as far as I can tell.  That might be worth fixing....
