The rule on litis pendentia

Dear PAO,

I filed a collection case against my brother to get reimbursement for my property which was transferred to a creditor pursuant to an amicable settlement. My brother opposed, claiming ownership over such subject property. Thus, during the trial of the collection case, the issue of ownership was fully heard. A decision was rendered in the case, which declared me as the owner of the subject property and ordered my brother to pay me a certain amount. He appealed the decision, and even filed another complaint challenging my ownership over the same property (annulment case). He claimed that the prior decision does not bar him from filing another case because, just like in ejectment case, the issue of ownership was passed upon by the court only for the purpose of collection, thus, it is not conclusive. Is he correct?
