 Oh! I think the point is a subtlety. Perhaps the paper means: regardless of whether charge is actually H_0 or 0, we claim I <= -H_0 and incoming charge <= H_0 - 0 = H_0 (if somehow the positive part were H_0 rather than 0). But since positive part is 0, the bound I <= -H_0 is even stronger than needed.
 
 Actually reading again: "Equation ~(eq:scalar-type-zero) gives
-$I_{s_i}(0;q,Z)le-H_0$, which covers its incoming charge."
+I_{s_i}(0;q,Z)le-H_0, which covers its incoming charge."
 
 Hmm. So the claim is I <= -H_0 and the incoming charge is <= H_0
 (maybe == 0 which is <= H_0). So the sum I + incoming charge <=
