It indicates that the person was close to death but did not actually die. So, in this case, "near" suggests proximity to a life-threatening event, but not quite reaching it.

A near-death experience refers to a situation where someone almost died but survived.

In English, "near" often implies something that is very close to a particular point, but not necessarily reached. It can refer to both physical and figurative proximity. In this context, it's used figuratively to describe being close to death.
