A bit of an OT note, but if you had the power of a charging horse behind it, just about anything "could chop a man in half from shoulder to hip". Even an dull iron bar. That particular example is less about blade construction and more about power transmission.
For that period, apparently not. The Brits had had a bit of a tough time with it, and wounds delivered might be painful, but not necessarily lethal. Some of the blades could be somewhat light...good for a thrust perhaps...but not all that good for cutting through a man.
Note, too, that a horse charges forward. A downward slash as described is on a more vertical plane. The horse transmits energy to a thrust, not a slash.
I think it was Christopher Amberger's "The Secret History of the Sword" that discusses this. I have it upstairs...and were I more mobile I'd run up and get it for you and look up the reference. If you're in a bookstore I'd advocate checking out this book. He goes into the slash versus thrust argument quite deeply...("A pun sir! Oh, touche!")...and he's an advocate of the slash, and a sabre exponent.
An instant stop, then as now, is desireable. Not all people will lie down when receiving a heavy wound, as we've learned in Somalia, Afghanistan, and Iraq with the ammo we're using in the M-16/M-4 family of weapons. Should you be fighting with a blade and NOT stop the guy, he could deliver an "AD" technique...i.e., "after death" wherin he is mortally wounded and yet takes you to the grave with him.
Of course we all know people, too, who would get a nick and faint.
As to slash versus stab...I advocate both. Know what will be most likely to drop a guy instantly and go for it. Use whatever is necessary to get to that point as quickly as possible.
