Something maybe wrong with bi_21_gsql

I am practising those examples which you guys put in github.I found one that mayby has something wrong.

The original like this:
“accLikeCount =
SELECT s
FROM vZombie:s
-((<Post_HAS_CREATOR_Person|<Comment_HAS_CREATOR_Person):e1)-(Post|Comment):t1
-((<Person_LIKES_Post|<Person_LIKES_Comment):e2)-Person:t2
WHERE t2.creationDate < endDate
ACCUM
s."@“likeCount += 1,
CASE WHEN t1.”@“isZombie THEN s.”@"zombieLikeCount += 1 END;”

I modified it as the following:
" accLikeCount =
SELECT s
FROM vZombie:s
-(Has_Creator_Reverse>:e1)-(Post|Comment):t1
-(Likes_Reverse>:e2)-Person:t2
WHERE t2.creation_date < endDate
ACCUM
s."@“likeCount += 1,
CASE WHEN s.”@“isZombie THEN s.”@“zombieLikeCount += 1 END;”

The case condition should be person’s zombie, not post or comment’s.

Would you agree that logic?
