confused with name in the pic

typedef struct A_Expr

{

    pg_node_attr(custom_read_write)

    NodeTag     type;

    A_Expr_Kind kind;           /* see above */

    List       *name;           /* possibly-qualified name of operator */

    Node       *lexpr;          /* left argument, or NULL if none */

    Node       *rexpr;          /* right argument, or NULL if none */

    int         location;       /* token location, or -1 if unknown */

} A_Expr;

I run a sql like select a,b from t3 where a > 1; and I get the parseTree for selectStmt:

why the name is '-' but not '>'?
