I believe direct addressing is the correct mode in this example, meaning that you could load 4 as the address containing the data required by the instruction. If you stored 4 in a register and used register addressing, then the value 4 would be the literal data used by the instruction, rather than a pointer to the required data.

In the first paragraph:
"addressing mode and specified the %eax register, and the %eax register contained
the value 4, whatever value was at memory location 4 would be used. In -->direct
addressing<--, we would just load the value 4, but in indirect addressing, we use 4 as
the address to use to find the data we want."
Would it be "register addressing" instead of "direct addressing"?
