It's important to understand that edge trimming is operating not on triangles level, but on mesh element level (mesh element is continuous group of polygons that are connected to each other by edges). It projects a ray from selection center of each mesh element towards distribution object, if the ray hits surface that is designated as trimming area, whole element gets culled, if it does not hit trimming area, the element gets rendered. Certain types of foliage, like bushes, doesn't work well with edge trimming, since they have long horizontal branches that are populated with small leaves. There's not much you can do about this, except... if you have lots of free time, you could break long branches into smaller chunks, so they could be better handled by edge trimming.
