They probably mean that with this type definition:

  struct S { int i; double d; };

the declaration

  struct S x;

can be seen as a shorthand for

  struct { int i; double d; } x;

Indeed, both declarations will declare a variable x that is
a struct type with an int member i and a double member d.

But there are subtle differences. For instance, with

  struct S x;
  struct S y;

x and y have the same type, and can be assigned to each other, like in

  x = y;

but with

  struct S x;
  struct { int i; double d; } y;

x and y have different types, and cannot be assigned to each other:

  x = y;

is not allowed.
