hashcat unexpected output from "s" Rule

[M@LIK]

One rule at a time (Starting from left) applied at the whole line:

Code:

ABCDEFGH + sAB = BBCDEFGH
BBCDEFGH + sBC = CCCDEFGH
CCCDEFGH + sCD = DDDDEFGH
DDDDEFGH + sDE = EEEEEFGH
EEEEEFGH + sEF = FFFFFFGH
FFFFFFGH + sFG = GGGGGGGH
GGGGGGGH + sGH = HHHHHHHH
HHHHHHHH + sHI = IIIIIIII
IIIIIIII + sHI = JJJJJJJJ
JJJJJJJJ + sHI = KKKKKKKK
...
ZZZZZZZZ + sZA = ZZZZZZZZ

Get it handsome? xD

This is one of the thing I "smelled" as "wrong" on the the other thread.
