使用管道符拼接多条GO语句时会自动聚合输入点吗，例如
GO 1 STEP FROM “Tom”, “Ken”, “Jerry” OVER use_app YIELD id($^) AS person, id($$) AS app | GO 1 STEP FROM $-.app OVER * YIELD id($^) AS src, id($$) AS dst
假设第一条GO语句查出的结果是
Tom->WeChat
Ken->WeChat
Jerry->WeChat
那第二条GO语句会分别以第一条结果里的三个输出WeChat出发执行第二条GO语句吗？还是说会对第一条GO语句的app进行聚合，只剩一个WeChat元素，然后执行第二条GO语句？后者性能应该比前者更高？
另一种情况，例如
GO 1 STEP FROM “Tom”, “Ken”, “Jerry” OVER use_app YIELD id($^) AS person, id($$) AS app | GO 1 STEP FROM $-.app OVER app_to_company YIELD id($^) AS app, id($$) AS company, $-.person AS person | GO 1 STEP FROM $-.company OVER app_to_company REVERSELY YIELD $-.person AS person, id($$) AS app
这种需要将第一条GO的person一直往下传递到最后一条GO，又是否会自动聚合输入点呢？
