This was added for the VCE dual instance feature and it tries to delay flush such as the flush is done only every second frame. For this it requires applications not to call vaSyncSurface after each vaEndPicture, otherwise every frame will be flushed. When this was implemented in 2016, libva and applications were different. Now applications will always sync surface after each end frame, making this feature completely non-functional. Another issue is that this is incorrect, the flush cannot be delayed and every vaEndPicture needs to flush. This is needed to ensure interop with other APIs (eg. sharing dmabufs with GL) works correctly. Delaying the flush would also mean submitting the same surface every frame for encoding (and changing the surface contents before encoding each frame) will not work.
