G4IKZ (6m) - turning his beam?

Nick G4IKZ (18km) has been spotting me some 24dB weaker on 6m WSPR in the last 30 minutes or so. I suspect he has just rotated his horizontal beam, maybe towards the USA or Caribbean in the hope of seeing some super-DX by multi-hop Es. I am using just a V2000 vertical (omni) and where his beam is normally aiming (Europe?) the cross-polarisation loss is minimal.
