Ray, in the demonstration of the strikes you see that the strikes reach, what happens in freeplay, is that for safety, the fencers parry stepping back, and even if not all but most strikes would hit if the defender stayed in place, the distance is always kept.
In freeplay with wood, a hit means a broken bone immediately because we strike intensionally without control, so for safety, distance is kept that way, but the attacker always aiming to strike to the body and reach the opponent.
To practice safely and do full contact, we do it with projections, like this:

here actually ending with a void and counter attack:)

however, a skilled fencer should be able to parry in place, as Nuno Mota shows here:

The kind of practice we do call "jogo" something like "playing" or "game" is intensionally extended as you well mentioned for demonstration but also actually as training practice(is the traditional way to practice), a real fight does not last that much exchanges, as do happen with protections. closing the distance is not prohibited as you see in some demonstrated counter attacks, but we fight in a way to avoid close combat, and take advantage of the weapon instead of going for close combat where a bigger guy would have an advantage that he doesn't have at fencing distance. that is great for self defense specially against more than one guy, to keep him far when you don't want do be grabbed.
