HA Override value set different per Peer

Hello community,

I was looking at an example of A-P HA configuration where FG01 was needed to be always the primary. They enabled override on FG01 and set a higher priority, so far so good. However..... I got lost when they said that we needed to keep override disabled on FG02. I did not understand why. The way I see it, the override state should be the same in both devices.

In my mind, setting Override in one FG and not in the other, could cause a split brain scenario, due to the fact that FG01 will look first at Priority and FG02 will consider HA Uptime first, so, its possible that both FG don't get the same verdict....am I Right or not? Could anyone please clarify this situation?

Thank you all!
