Does anyone have an idea why G-ZBLA is doing a LHR to LHR flight for 4 hours?

it turned back from Doha on Feb 28th I’m assuming because of the air strikes in the Middle East. But this seems a bit random

or is G-ZBLD coming back and is somehow showing under G-ZBLA? I know IAG said they should be done with the 787 groundings in May
