[web-nfc] The description of multiple scan() calls is a bit vague (#351)

Honry has just created a new issue for https://github.com/w3c/web-nfc:

== The description of multiple scan() calls is a bit vague ==
In [scan() method](https://w3c.github.io/web-nfc/#the-scan-method), spec says: 
>Multiple consecutive calls to the scan() method from the same origin create filters which are in OR relationship.

Multiple calls to the scan() method may have following two scenarios:
1. Multiple scan() calls from different NFCReader objects in the same origin, they create various filters which should be independent. This does not apply to the "OR relationship" I think.

2. Multiple scan() calls from a single NFCReader object. Looks like it could only create one filter for a reader object. Maybe the latter call to the scan() method should override the former one. But this should be explicitly explained in the spec.
