Yes it is. From the smb.conf man page: 

          [The] resulting  UNIX  mode  is then bit-wise 'AND'ed with 
this parameter.
          This parameter may be thought of as a bit-wise  MASK  for  
the  UNIX
          modes of a file. **Any bit not set here will be removed from 
the modes
          set on a file when it is created.**

So the masks define which bits CAN be set, the force modes define which 
bits WILL be set.
