Read it again.
The Developer capacity is 3 rolls of 120 and the Bleach capacity is 10 rolls per liter. You can reuse the bleach but must discard the developer after one use. Also, the shelf life of the bleach once mixed/used is 8 weeks. It's not necessary to use a stoppered bottle with the bleach as it needs air.
I must admitt Kodak's C-41 chemistry and availability is awfully confusing. I E-mailed them regaring the availability for Bleach III.
BTW, the pub you posted is not for the SM kit.
