Why do we not need $\ce{H2SO4}$ as an acid catalyst for the di-nitration of veratrole?

enter image description here

Why does the 2nd nitro group go to positions 4 or 5, following the directing effects of the methoxy-group? Doesn't the first nitro group, that has been substituted intoonto the compound, have any effect on its position?
