Sure.

There is no such thing.  This is illegal string syntax.

Have you tried what happens if you do
(insert "\\%")
in a buffer?

Sure.  But you don't expect when typing
(insert "x")
that the quote characters end up in your buffer, as they are merely
part of the string syntax.  So why do you expect that the doubled
backslashes, which are merely part of the string syntax, end up in the
buffer?
