This is impossible, each event has its own unique ID - the SN parameter in the query string. You will also get an exception when you attempt to execute an action for an activity that does not exist and in this example, only one can exist in a point in time. It might be that having two Client events with the same name interferes with your SmartForm's logic if it makes use of that to change information on the form. Maybe renaming the events to be more relevant to the activity it lives in might avoid some confusion. Your best bet would be to have a look at the Reports, that will confirm which one was completed.
