I dont think its QWERTY related.
I even tried shifting the values by the amounts defined in this table (its the difference between the green hex value and the code given to us):
554455454 455555 554444 4545454 21310|15|12|12|2 2|15|27|12|12
SKEGRJAIH FWBLOX OPGFEH ARFSAJC HDJAR| W| Y| Y|H H| W| X| J| Z
I got:
jvulocgdz kuebfm fglkuz gokjgcm kfzsr j k k k k j c e y
Which looks completely ridiculous now

especially the 'kkkk' in the last 2 words.
