How can a SID's MEA be above its top altitude? The SID below has a Top Altitude of 5000 feet, but its Minimum Enroute Altitude (MEA) is above 5000 feet. Why?

I am referring to the SID depicted below, from FAA's SID charts (plate and departure route description). As one can see, the Top Altitude is 5000 for this particular SID. Nevertheless, if we take a look at the MEAs of its transition route, we notice values much greater than 5000 feet (8000, 11000 and 15000 feet).

Could someone explain to me the reason behind this?
Top Altitude is the initial climb altitude for a 'climb via SID' instruction, unless otherwise is stated.


  TOP ALTITUDE– In reference to SID published altitude restrictions the charted "maintain" altitude contained in the procedure description or assigned by ATC.


Initial climb altitude/level is not directly related to the MEA. It has more to do with radar acquisition, noise abatement, and clearing obstacles.


  MINIMUM EN ROUTE IFR ALTITUDE (MEA)− The lowest published altitude between radio fixes which assures acceptable navigational signal coverage and meets obstacle clearance requirements between those fixes. The MEA prescribed for a Federal airway or segment thereof, area navigation low or high route, or other direct route applies to the entire width of the airway, segment, or route between the radio fixes defining the airway, segment, or route.
