Lando didn't suggest it to cover Leclerc. That was a fiction concocted by the Sky broadcast crew.To me it still feels like Lando wanted to see what Oscar’s side did first, he knows Oscar has pretty much said all he cares about is finishing before him.
That’s why imo Lando suggested for Oscar to go first to cover Leclerc even though it wasn’t needed.
Lando also covered himself by saying that he didn’t want to be undercut, he wanted his cake and to eat it too.
“I want all the benefits of pitting first, whilst getting the benefits of pitting second”
Lando wanted Oscar to go first in case there was a safety car, which would have given Oscar a gain and allowed him to overtake Lando.
Leclerc was never a threat to Oscar's position, unless Oscar had a horrible pit stop (as Lando did). At the rate he was closing, he wouldn't have threatened Oscar's position for another 10 laps - and there were only 8 laps remaining in the race.
Lando was entirely within his rights to ensure that he wasn't undercut by Oscar - and the team would have been right to ask Oscar to redress in the extremely unlikely case that this happened. In the end, Lando copped a slow pit stop, which had nothing to do with undercutting.
