Interactive rebasing last picture (1-8)

After the last example of rebasing in this page there is an image showing the new rebased repository.

The first commit after Z, states that I'equals B+C+, I'm not sure but that would not be C+Xinstead?

Let's step back for a second. We cherry-picked C and X. At some point, we want to merge L into Z. The Z branch contains the X commit, aka. we don't need to apply it a second time since it's already there as the base of I is a new child of Z. However, we need to apply B in order to get to C because it's the parent of C (or build-up, requirement, prerequisite, whatever you want to call it).
