Native English speakers, could you please help me with these issues?

Are both these sentences correct (and do they mean the same):

a) "The chat room is always run by a teacher for a period of 4 hours, who afterwards was replaced by another teacher for the same LENGTH OF TIME, and SO ON."

b) "The chat room is always run by a teacher for a period of 4 hours, who afterwards was replaced by another teacher for the same LENGTH OF TIME, and SO SUCCESSIVELY."

    The chat room is always run by individual teachers who change over at the end of successive 4-hour shifts.
