One person's "week" is another person's couple days. Plus, a week of subsistence rations isn't the same as a week of rations that would keep you functional. It's all a matter of perspective.

My Aviator Survival Pak is designed to keep 2-people functional for 2-3 days, depending upon climate. Some might call that a week's worth.

Finally, one must never take anything in the media during an incident at face value. Always keep that in mind.
