I don't personally use nested TRY/CATCH so this is from what I saw Ken L do in a session years ago. With Try/Catch you can THROW a exception object which contains the error info. This can be consumed within the CATCH clause. With nested Try/Catch, you may need to pass that object to the next nevel up so it can be seen by the next level.

There is an explanation in the help on this

If anybody has real experience with this, please chime in.
