I execute two queries on my RedisGraph and get an error.

Redis version:7.2.0
RedisGraph version: v2.12.10
operating system: windows 11
API：Cypher version 9

To create graph:
input01.txt

Query pair:
Ⅰ: MATCH (dqowryyf:Person)<-[]-()-[]-(wscygnst:Movie)-[]-(milyqbqp:Person) RETURN DISTINCT count(milyqbqp)
Ⅱ: MATCH (dqowryyf:Person)<-[]-()-[]-(wscygnst:Movie)-[]-(milyqbqp:Person) WHERE wscygnst=wscygnst RETURN DISTINCT count(milyqbqp)

I think these two queries are equivalent, but the first returns 13 and second returns 15.
