Ah, just found this in the WFS 2.0 spec:
BBOX: This is a convenient and more compact way of encoding the
BBOX constraint based on the gml:Envelope.
The BBOX operator shall identify all features whose geometries
spatially intersect the envelope.
The sentence makes me think all geometries should be taken into account
Cheers
