When saving an MS Office document with password, what is the difference 'Encryption with password and 'General Option'

With EE's help we were able to identify the encryption used in MS Office 2010; 128-bit Advanced Encryption Standard (AES) is used (others also available).  Up-to now, we found two ways of saving a document with password:

"File >> Encryption with password" and "Save As >> General Option".
(see pic below)

file-encryptsave-as



Is there a difference between the two?

The General options give the option of having separate passwords to open and modify whereas the Encryption with password just has the option to encrypt the document with a password but provide the same level of security.

But both option encrypts the document the same way? In other words, if we use "save as >> General Option" it doesn't mean is less secure or a different encryption that in "File >> Encryption and Passwors"?
