[SW] 21470 kHz - BBC Dari & Pashto, A'Seela - nice signal in Poland, Jun 28 2024

This is the reception of BBC broadcasts to Afghanistan, beamed from Al Seela, Oman on 21470 kHz.
BBC transmissions to Afghanistan from Oman are aimed approximately in NE direction, while I am located roughly NW of this site, so I'm off-the side, and likely in a null of their directional arrays. Hence, I always experience weak signals from those beams.
However, on 13m band, with its very low noise floor, a decent reception is possible.
Now, for some reason, Aoki broadcast database (via short-wave.info) lists Dari broadcasts as running exactly from an antenna beaming 63deg, while Pashto ones are from a 35deg beam. Why such a difference, especially if it wasn't there in the past?
Apparently, the BBC treats some audiences better than others regarding shortwave broadcasts...
