Yes, matrices are a truly classic application for multiple index registers. That's why I didn't start writing such programs before I had an HP-41. ;-)
Here you can easily code such things as

RCL IND 03
RCL IND 04
x
ST– IND 05

Thanks.
I’m glad you see my reasons for asking the question.

Just so you know, although the SR-52 was TI’s answer to the HP-65, I wonder how (if the HP-67 was HP’s comeback to the 52), the 67 answered the challenge of the SR-52’s multiple indirect registers and the EXC (TI’s Exchange memory) commands.
