Multiple edgetype, go statement behavior

[panda-sheep]

use case：

CREATE TAG DID(did string);
CREATE TAG UID(uid string);

INSERT VERTEX DID (did) VALUES 11:("n2");
INSERT VERTEX DID (did) VALUES 13:("n22");

INSERT VERTEX UID (uid) VALUES 11:("n3");
INSERT VERTEX UID (uid) VALUES 13:("n33");

CREATE EDGE GID_DID(create_time timestamp,update_time timestamp);   
CREATE EDGE GID_UID(create_time timestamp,update_time timestamp);  

INSERT EDGE GID_UID(create_time, update_time) VALUES 11->13: (1597914255, 1597680000);
INSERT EDGE GID_DID(create_time, update_time) VALUES 11->13: (1597914255, 1597680000);

go from 11 over GID_UID,GID_DID where GID_UID.update_time >= 1597680000 or GID_DID.update_time >= 1597680000; （1） go from 11 over GID_UID,GID_DID where GID_UID.update_time >= 1597680000 ; （2）
What is the expected behavior of the go statement？
