Veer vs. Inside Zone blocking

I've seen several discussions on this, but I'm still not sure I see much of a difference between the two. We ran Zone Read last year, and this year I've been looking at a couple of DeMeo's books. I'm not sure what the difference really is, the QB is reading the same DE whether you're running zone or veer, am I correct? The OT follows Veer rules instead of pure zone, but other than that, the plays look similar to me. Is the RB aiming point slightly different? It seems to hit more backside. OK, here is the other issue I'm confused about... when people are discussing the backside cutback on veer, is it in fact the side of the C opposite where the RB aligned? In the zone play, we termed the side opposite where the RB aligned as the frontside, as his aiming point was this G (ie. RB offset to the R meant he was aiming at LG, therefore we called the play a Zone left, with left side being frontside). In the veer play from gun, is the "frontside" the side the RB aligned to? Thanks in advance, hope some of this made sense,
