Why are there multiple DFG edges from a single node?

[fwendland]

Situation

I have the C code:

#include <stdlib.h>

struct s {
    int a;
};


struct s * S_new(int a) {
    struct s *s = malloc(sizeof(struct s));
    s->a = a;
    return s;
}

void fun() {
    struct s *s_ptr;
    s_ptr = S_new(1);
}

The corresponding CPG visualized in Neo4j is (excerpt):

Question

Why are there two DFG edges starting from the S_new call expression?
