[abc-users] Tracematch matching semantics

I have a question about the matching semantics that tracematch supports.

given a really a tracematch, e.g. the simple one given below, which is
matching two subsequent calls to save: When two 'save' are detected, the
tracematch gives a match. However, when a third 'save' is detected, a new
match is given (rather than waiting for a fourth).

Is this the intended semantics of tracematches?

public aspect MatchTwoSaves {
   pointcut save(Editor e): target(e) && call (* Editor.save(..))

   tracematch (Editor e) {
     sym save after returning: save(e);
     save save {
       // we got a save+save match, now do something with it

Best regards,
