This is referring specifically to the last video. There's a move you tend to do a lot where you spin the saber and take a step forward while striking overhand at the same time. My partner does this a lot and I've learned it as well as a couple defenses against it.
Yes there's a name for that in Olympic and turns out I've been using the wrong one the whole time. So I don't know what that's called. As far as I'm concerned every flip but the last one is a feint, for those opponents who wait for your attack to finish then riposte.
If you like that, you should check out Vickerz in our club, who does the same but going the other way. Makes for a wicked undercut. Very hard to parry correctly. Check out this vid around 0:54.
Where as Ryan in his defense seems to use heaven and earth kata a couple times, sweeping upward block the goal to push your blade up out of the way and trying to smash down. Even when the 'block' doesn't connect, it's followed by the downward stroke.
Ryan probably uses the most committed stances in our club, which I think you're referring to. He doesn't block a lot but when he does they are powerful.
Round 2, on Ryan's first touch it looks to me like he used a ballestra. Or some type of slightly exagerated lunge. There's times looking at the way you move your saber where I think you're trying to use florentine style except that you only have one blade.
I watched it and it looks like a cross-step-lunge or a short fleche (we call it a flechette). A ballestra, in Olympic, is just a forward hop, often followed by a lunge. It's more like what is called a "Hyper Jump Step" in this video from TPLA around 2:55:
