Checking if different versions of a SAP Notes are implemented or not

Through snote, I had looked at the note log and below is how it looks like.

06/05 - SAP Note abcd in version 0001 downloaded

06/05 - processor had been changed

06/05 - Processing status changed to 'in processing' (version)

06/05 - User had confirmed that notes has been read

06/05 - SAP note locked in request xxxxx

06/05 - Correction instructions 0101238787 0000236566 0001 completely implemented

09/20 - SAP Note abcd in version 0002 downloaded

Now my question is shouldn't there be a text for time stamp 09/20, in the log, which says that Correction instruction 0101238787 0000236566 0002 completely implemented, if the notes had been implemeted correctly ?

I am just thinking that version 0002 is donwloaded but am wondering if it actually got implemeted or not !!!

How do I know if the notes had been implemented correctly through a technical means rather than checking the system functionality ?

Thanks
