Any point in doing cashfusion if i sell the bch on p2p platform for bitcoin?

Is there any point in doing CashFusion with BCH bought from an exchange (with kyc) if I sell it on a p2p platform (without kyc) to get Bitcoin? If i make a purchase with that bitcoin can it be traced back to the original exchange with kyc? Basically what i want to know is if doing the cashfusion enhances anonymity if i sell it on a p2p platform anyway
