Scandal is what mr. Horner brought to Red Bull.
This is inter team racing dynamics. Oscar was given opportunity to pit first to protect against Leclerc. Lando lost the spot because of it. Just like in Hungary, the driver that was given the advantage was asked to give it back. If they didn't, the drivers would hurt each other next time around because the car ahead would not allow the other driver to pit first, thus opening them up to undercuts from other teams.
Imagine we are running P1-P2 with P3 close behind, P3 goes to undercut and then our lead driver doesn't allow P2 to pit first to protect himself from P3, but he pits instead. So our P2 guy has to wait two laps until he can pit to protect against P3. What they did here is allow P2 to pit first, with the understanding that the undercut gain is not allowed to change positions between them. Completely logical view for the team. Oscar gained from it in Hungary 2024, Norris gained here (with the difference that Norris was much faster in 2024).
