Riddle me this batman...

I was parsing some RSZ to review ... and i found the following..

RSZ with a short S .. used on 2  SEPERATE wallet addresses.. IDENTICAL RSZ ..   
Does this indicate a problem with the signing process? Its recoverable in regards to keys but i fall short of that...

So just wondering if anyone else has seen this before...
thx,

ps - dont really want to release the sigs..  and they are from the chain.
