Rumour has it that the wx at Aberdeen meant that, as a destination, an alternate was required. An L2 could probably fly back from that rig with a reasonable payload, and no strong headwind (as was the case that day, direct to Aberdeen. But since an alternate was required, it could only probably do that with a fairly low payload,if at all (depending on where the alternate was). To pop into Sumburgh, nearly on the way, to gain a few extra passengers-worth of payload is obviously the sensible thing to do, and common practice.
