16bit versus 32bit?

I was wondering about one line quoted above:
...the ring 0 supervisor of Multics of 1973 occupied about 628K bytes of executable code and read-only data. This was considered to be a very large system. By comparison, the size of the SELinux module with the example policy code and read-only data has been estimated to be 1767K bytes.
I am not sure if this is an apples and oranges comparison. One the two architectures used different instruction widths. Second, the number of instructions are comparable. If they were able to code the Multics code for an Intel processor/hardware and get the same size then I think the comparison would be valid.
