Error in the original?

I think I found an error in the original (well, windows re-release) of T7G... I can't explain it any other way. If you don't understand assembly, this will probably be lost on you, but I'm going to paste it in anyway:

.text:00404B5A                 mov     eax, [ebp+var_C]
.text:00404B5D                 imul    eax, 3
.text:00404B60                 mov     ecx, [ebp+cursor_file]
.text:00404B63                 mov     dl, [ecx+eax]
.text:00404B66                 mov     byte ptr [ebp+var_1C], dl
.text:00404B69                 mov     eax, [ebp+var_C]
.text:00404B6C                 imul    eax, 3
.text:00404B6F                 mov     ecx, [ebp+cursor_file]
.text:00404B72                 mov     dl, [ecx+eax+1]
.text:00404B76                 mov     byte ptr [ebp+var_1C+1], dl
.text:00404B79                 mov     eax, [ebp+var_C]
.text:00404B7C                 imul    eax, 3
.text:00404B7F                 mov     ecx, [ebp+cursor_file]
.text:00404B82                 mov     dl, [ecx+eax+1]
.text:00404B86                 mov     byte ptr [ebp+var_1C+2], dl

Can it be true? It accidentally uses the green channel twice instead of the blue one. In something as important as the cursor handling it seems unlikely that it would go unnoticed. But then, this is in a fairly obscure part and wouldn't affect all colours in the cursor. Interesting.
