It's redundant - see (info "(elisp) Variable Definitions"):

     If a ‘defcustom’ does not specify any ‘:group’, the last group
     defined with ‘defgroup’ in the same file will be used.  This way,
     most ‘defcustom’ do not need an explicit ‘:group’.

If :group is specified, it will most of the time mean the defcustom should
be assigned to some other, not to the default, group.  So it's better
style to not explicitly specify the default.
