 On the face of it, (EDR) seems to capture precisely one strongly intuitive notion of existential dependence; or more accurately, one direction of that notion. The intuitive idea behind this notion is that if y does not exist, then the dependent entity x does not exist. For example, when it is said that a particular event, such as the assassination of Caesar, depends for its existence upon Caesar, (EDR) seems to explicate this appropriately in terms of the fact that the assassination could not have existed if Caesar had not existed to be assassinated. Some other assassination, we may suppose, could have existed at that very time and place, but for that very assassination to have existed, Caesar himself had to exist.
