Can anyone explain "ignore previous" feature of Wait on Notification function?

Can anyone explain "ignore previous" feature of Wait on Notification function?  I have read the help description and other material and I just don't get it.  Reference to any good articles I can read will be appreciated.

Thanks in advance.

Hi VI Joe,

if the "ignore previous" input is true, then you only get the notifiers which arrive if you are waiting in the "Wait on Notifiacation" function. If there is a notifier before this function is executed, then you don't see it.

Edit: See the attached example. If the constant is true, then the vi will wait on a notification because the previous is ignored, if the constant is false, then it receives the notifier. 

Hope it helps.

Mike
