GO...FROM...BIDIRECT can't work

INSERT VERTEX bnc (value) VALUES "player999":(2);
INSERT EDGE follow (degree) VALUES "player102"->"player999":(70);
INSERT VERTEX bnc (value) VALUES "player888":(0);
INSERT EDGE follow (degree) VALUES "player999"->"player888":(90);

go 1 to 3 steps from "player101" over follow
where follow.degree>80 or $$.bnc.value>0
yield edge as e;
检索结果正确

go 1 to 3 steps from "player101" over follow BIDIRECT
where follow.degree>80 or $$.bnc.value>0
yield edge as e;
检索结果有问题：1、超过3跳；2、有跟起点不关联的子图。
