It is, assuming that IndexedDB is based on the origin of the document. The 
spec doesn't mention it because IndexedDB isn't part of the HTML spec. 
Note that the sentence you cited is non-normative (or rather, it contains 
no normative statements), so that whether it mentions IndexedDB or not 
doesn't change anything about what the spec says.
