How would Joseph Smith know about alternate parallelisms?

Alternate parallelisms contain words or phrases which are repeated in the same order (A-B-C-A-B-C). Some examples of this form of parallelism contain many elements such as 1 Nephi 9:3–4:

A. I should make these plates,
B. for the special purpose that there should be an account engraven of the ministry of my people.
C. Upon the other plates
D. should be engraven an account of the reign of the kings,
E. and the wars
F. and contentions
G. of my people;

A. wherefore these plates
B. are for the more part of the ministry;
C. and the other plates
D. are for the more part of the reign of the kings
E. and the wars
F. and contentions
G. of my people.

Nearly 400 examples of alternate parallelisms are found in the Book of Mormon. How would Joseph Smith manage to dictate such literary techniques like this?
