The reason for this is to make it easier for system administrators to estimate when the scrub happens, for instance, if a scrub was done on Saturday, it always happen on Saturdays. On large zpools, scrub can consume a lot of time and I/O bandwidth, and having it happen on random weekday is not a good idea.
