There are various kinds of variable scopes in jBPM, and Seam does not take advantage of all of them. When a task is created, it gets a "copy" of all the process variables. When you write to a variable inside the scope of a task, it remains scoped to the task until the task ends, a which point it gets copied back to the process variable of the same name.
