You are correct - there is nothing standard about this. The TOC point is defined in the LOA or other agreement between adjacent ANSPs or units within the same ANSP. This may be a clean handoff at the TOC point, or there may be conditions, such as back coordination required for any or certain clearance changes within a parameter of crossing the TOC point.
The whole 'released' thing is so old fashioned.
