Narrative:

During preflight we received a dangerous goods notification form indicating that we would have dry ice type goods onboard. After briefing and door closure the ground crew came on and said they were ready for push. From [gate] no push clearance is required; only an advisory call to ground. After checklist completion I released the brakes so the crew could scoop us. It was then that I realized we had not yet received our final dg (dangerous goods). I notified the push crew to hold as we had not yet started to push. We received our final dg and after review I notified the ground crew that we were cleared to push. We then pushed. Although we did not actually push prior to the final dg as stated in the fom; we had released the brakes. After a discussion we were not sure if brake release had constituted a push even though we had not moved prior to the final dg. The flight continued to destination without issue and was fully debriefed.

Although we did not actually push prior to the final DG as stated in the FOM; we had released the brakes.
