[Grammar] Is this comma splice?

[rambharosey]

Jack did not like beer, he nevertheless had beer with his friends, and these meetings helped Jack grow his network.

There are three Independent clauses here:

1) Jack did not like beer
2) He nevertheless had beer with his friends
3) These meetings helped Jack grow his network

Since these Independent clauses are connected by "and", this should not be a comma-splice.

However, my esteemed colleague mentions that this is a comma splice.

Can an expert please clarify.

 

[rambharosey]

Yeah, but there are three Independent clauses. Conjunction "and" is present before the last Independent clause.

 

[Rover_KE]

The comma splice exists between the first and second clauses.

Thanks Rover. Can you please explain further. For example, how about the following:

Jack likes swimming, his brother is into cycling, and his sister plays basketball.
