Some of the kit instructions are extremely lacking and don't tell you when you need to wash, or put them in as a footnote that's not very clear at all. There's a long APUG thread (also linked from my howto) about the Rollei kit that discusses the washing issue and shortfalls in kit instructions.
Yes! Absolutely true. I used the Rollei kit for my film developing and they don't tell you to wash in between steps. They only suggest a pre-wash and that's it.
