CaitVi worked in S1.
Because Caitlyn wasn’t a full part of the oppression that Piltover inflicted upon Zaun.
Cait was a newbie enforcer , a body guard at best , up until that moment she hadn’t hurt the Zaun or imposed laws or commanded enforcers.
She wasn’t a direct participant in the oppression unlike the Councillors or Marcus and other commanding enforcers.
That changes in S2 when Caitlyn starts to actively oppress Zaun , gas civilians , send people to jail for questioning even tho they’re not involved , impose martial law.
Cait became an oppressor at that point. And is not held accountable for it and barely redeemed from her actions. ( show wise if I can take her redemption which I don’t , it’s only for what she pulled on Vi , she didn’t redeem herself for Zaun , giving Sevika a council seat where decision are made by voting counts for nothing, cause it’s gonna do nothing)
Zaun is still oppressed under Piltover’s rule ( Pilties still look at Zaunites with distaste and see them as lesser and the council seat is almost useless)
Caitlyn is still a sheriff with full power and Vi has nothing . A worrying power imbalance.
Thus Cait and Vi in S2 became oppressor X oppressed.
