Does really tall height make the belly a very vulnerable target in a swordfight?

In historical fencing (especially smallsword/rapier) tall guys (6'5"+) usually get stabbed right into the belly by short fencers, especially on counterattacks. And on real rapiers, a short opponent would probably concentrate on a tall guy's belly even more, cause its a soft fleshy target with no bones and the blade can get plunged deep into it without getting stuck anywhere (like in the ribs, for example). And a belly stab would actually be the most brutal and excruciating stab.

What are your thoughts on that?
