No. It doesn't "make" digraphs.

What it was intended for was to indicate that a sequence
of characters (which could be a digraph) are to be treated
as a unit by some process which is sensitive to the presence
of a CGJ in such a sequence. An example is some process
(e.g. collation) which might need to treat some examples of
"ch" as non-digraphic and other instances of "ch" as a
unit, i.e. as a digraph.

For the purposes of *that* process, the sequence <c, CGJ, h>
would *behave as a digraph*. Some other process, however,
might totally ignore the CGJ, and for the purposes of that
*other* process, the sequence <c, CGJ, h> is just a "c" and
and "h" with a default ignorable character in between them.
