Narrative:

Aircraft #1 overflt at 8000 ft. Aircraft #2 and #3 arrs enter at 10000 ft. I was the recently relieved controller at this position. During the traffic portion of my briefing; I descended the first arrival to 9000 ft and said 'I'll let you take him through that aircraft at 8000 ft' and physically pointed at the overflt (aircraft #1). A few xmissions after I had completed my relief briefing and left the area; the relieving controller descended both arrs through the protected airspace of the overflt. Lack of situational awareness contributed to this occurrence.
