'Why does the pseudocode of _mm_insert_ps calculate %8?

Within the intel intrinsics guide, the pseudocode for the operation of _mm_insert_ps, the following is defined:

FOR j := 0 to 3
    i := j*32
    IF imm8[j%8]
        dst[i+31:i] := 0
    ELSE
        dst[i+31:i] := tmp2[i+31:i]
    FI
ENDFOR

. The access into imm8 confuses me: IF imm8[j%8]. As j is within the range 0..3, the modulo 8 part doesn't seem to do anything. Does this maybe signal a convertion that I am not aware of? Or is % not "modulo" in this case?
