actually the delimiter here is the single space in <" ">
of which there are two occurences.
you are stuck here with the ambiguity of
the single space occuring both between tokens
in the quoted material -- the strings --
and between the strings.

using <" "> as the delimiter gets you
unbalanced dQuotes in the first and last items.

why are you (attempting to be) doing this?
consider:
%Let String1 = footnote1: content;
%Let String2 = Some other footnote;
%Let String3 = my 3rd footnote;

either
footnote "&String1 &String2 &String3";
or
footnote "&String1" "&String2" "&String3";
produce your desired result

SQL provides a table with the text of titles and footnotes:

PROC SQL;describe table Dictionary.Titles;quit;

   type   char(1)   label='Title Location',
   number num       label='Title Number',
   text   char(256) label='Title Text'

PROC SQL;describe table Dictionary.Titles;quit;
footnote1 'text';
PROC SQL;select distinct *
         from Dictionary.Titles
        ;quit;

Title        Title
Location    Number  Title Text
F                1  text
T                1  The SAS System
