Most likely because Philippine Air is non-stop to MNL and CEB where as BR is a one-stop. Generally non-stops cost more in most cases.

If you look at these flights BR11/15/5/17/27/7/25 to BR271/261/281/233 on LAX/SFO/SEA-MNL/CEB/CRK route why do they end up being cheaper than Philippine Airlines which is spelled out in Taiwan as 菲律賓航空.
For starters on Philippine Airlines Eva Air competition on West Coast to the Philippines the flights that you're looking for are PR105/113/103/125 for MNL and CRK. While for CEB it's combination of the Philippine Airlines flights from LAX/SFO/SEA with MNL-CEB.
