In plain words
For karma that has already begun its course, experience and knowledge are its two natural results. Their coexistence is entirely logical, unlike what happens with other forms of karma.

Of karma that has begun to bear fruit, these two are indeed the results: experience and knowledge. Non-contradiction of those two is appropriate, whereas there is dissimilarity for the other.
