typo error on Figure 8.8 code?

[hokim72]

Is RAW correct
in #pragma HLS DEPENDENCE variable=hist inter RAW distance=2 ?
I think the following is WAR(write after read)
hist[val] = hist[val] + 1;
Could you explain why it is not WAR but RAW?
Is it because of his[val] read at i+1(right-hand side of the equal) after hist[val] write at i(left-hand side of the equal) ?
