Wow, as long as I’ve been using it I’ve never noticed, though I don’t actually use flex fields much. Like I said, logically a repeater field and a flex field is the same and the difference is if all fields in the each row of a repeater will be the same or if they can be different. From what I’ve seen here many people use a flex field when they should be using a repeater.
Anyway, the difference between block and row is the same for the flex field as it is for the repeater.
