I personally would not ask you to expedite all the way when directly underneath/on top of another aircraft. I work in london TMA and generally ask only for expidition thru a level before the cleared level in these circumstances. I'm sure most of my colleagues are the same. My feeling is that some controllers use the term far too often when it is completely unnecessary. When controllers use expedite in every second transmission I feel that they reduce the effectiveness when thay really do need it. A pilot on frequency hearing expedite every two mins may start to doubt how much control the controller actually has, i know I would!
