No worries. From what I understand of the debate (slashing vs thrusting cavalry swords), there were merits on both sides. And, supposedly, that 1908 Pattern Cavalry Trooper’s Sword was supposedly the ultimate cavalry sword of all times (you could, btw, slash with it too, though it was meant to be used as a thrust sword at the gallop).
Naw…it would depend on how good a horseman you were, I think. I’ve seen Brit practice manuals and cavalry sword drills, and you could definitely use it more than once. You can look it up, but essentially the tactic was to ride with the sword in front of you and pointed down at the enemy (who would, most likely, be fleeing…these were heavy cavalry tactics to be used in the face of a broken enemy after all). You ride down the enemy at a full gallop, use the sword like a short lance, and then allow the momentum of the horse to drag the blade free (mind, you need to be using a sword wrist strap for this). It, supposedly, takes less effort and puts the rider in less danger than standard slashing tactics in the same tactical environment.
Personally, I favor a curved blade myself. But then again, personally I prefer some kind of stand off weapon when I’m on horse back. 
Yeah, not all of the Brit innovations were exactly successful. Still…a hell of a lot of them were. Most of our own military, especially our Navy, derives a lot of our tactics and systems from the Brits. I think in this case it’s moot…by the time they were really adopting a thrusting type sword (and btw, for light cavalry they still used a curve saber type sword), swords were pretty much obsolete. Then again, swords were sort of obsolete for quite a while even before that, so there you go.
