There is no guarantee that the bundle image is going to be skipped all the times. There is a scenario with small chance of happening where the operator related image and the operator bundle image are in the same batch and the bundle image is executed first in the concurrent process, in this scenario if the related image fails, the bundle is not going to be skipped because it has been already mirrored.

One solution is to start using channels in the concurrent_worker.go to synchronize bundles and related images.
