RE: HP-15C expanded memory firmware: problems with matrix larger than 8x8

I wanted to try this patch to generate an Error 11, but I noted a discrepancy.
The original data (before patching) should be 000 at addresses 13F9-13FD, but I found different data in the original ROM:

13F9:08B
13FA:0E5
13FB:2D3
13FC:2C6
13FD:0F5

Did I miss something?
