In response to my own question... YES!  The mismatch in naming of workflow elements is nearly as bad as it can get, and there are few elements that simply map one-to-one.  Furthermore, the graphical elements are often "overloaded" with very different semantics, depending on context or attributes.  Examples:

BPMN "task" = JPDL "node"
  | BPMN "parallel gateway" = JPDL "fork" or "join" or both, depending on the transitions in or out.
  | BPMN "sub-process" = loop, ForEachForkActionHander, or super-state, depending on attributes
