The differences are superficial. VorNach can attest there is no technical difference in the two uses of the sword. Hopefully Nero will chime in on this as well. It is the similarities that make this stuff possible. A single handed blade style isnot going to be apprciably different from another. If they are legitimate.
Finally getting caught up.
Yes, I can attest to this.
Really though, what may be drawing some peoples attention away from the core principles and techniques that Master Nonymous is presenting is the structure of the form itself. As Bazzard noted:
in the earlier videos, the actual techniques are pretty similar; it's just that Eastern swordplay styles tend to look a little more......I dunno, 'dressed up'......when performing them.
There's a lot more movement than what we associate with "fencing" in this form.
When taken out of the strip it becomes more dynamic however when put into application it starts to become more linear again.
Here's a "historic" Makashi vs Djem So sample:
