No I don't think so, since they only set the N bit of the aggregation header if a) this is a keyframe and b) a sequence header is present. A keyframe with no sequence header (which an encoder might decide to emit) or a sequence header in a non-keyframe like you're describing will not result in the N bit being set. Hopefully that clarifies things.
