why Different Derivative path and XpUb able to sign transaction

Hey ,

I was playing with multiSig 2 out of 3 in sparrow Wallet
Wallet 1 : hot wallet in Sparrow wallet itself
Wallet 2 : CC (SEEDS X)+ Passphrase
Wallet 3 : CC (SAME SEEDS X as wallet 2 ) + Different Passphrase

But when i use Wallet 2 as complete different wallet (in single sig) it generate with derivative path of m/84'/0'/0' and gives XPUB xpub6C...agCXs . But when i used the same wallet 2 (seed X + same passphrase)in multisig (added by scanning QR while setting up) it generates derivation path of m/48'/0'/0'/2' with Xpub of xpub6ED....bGN . Masterfingerprint is same in both cases however
I thought transaction won't go through due to different xpub and derivative path .. but it successfully got signed and broadcasted in multisig

Any reason for following ..
