Media Server :: Why Application.clients Array Gets Disordered

I have been researching and I found that every new client is stored in application.clientsIf I have 3 students connected, lets say student1, student2, student3, and student4 if I made a trace :

for (var i = 0; i<application.clients.length; i++){
trace("student "+i+": "+application.clients[i].name);
}
