I think those 2 are trying to say is that at a point if you can use a palm style that is beyond that of a sword, then you reached the "no sword" stage. It's a point when a finger, palm, fist's energy can surpass the limits of the sword and what kyss of sword seems to suggest is that YG's Sad Palm has exceeded that sword limit. Another explanation could probably be, if the Greats and all know sword arts, then why don't they use sword arts if they're really better? Instead, they all choose to use the palm, finger, fist, etc techniques. This could be suggesting that those are more effective since you pretty much have nothing to hold back during major fights. Look at QZ sect. In ROCH, all the disciples used swords and even the QZ 7 used swords a lot. However, look at ZBT and WCY. Have you seen ZBT EVER use a sword? No, yet he knew it because he taught it to YLQ. And though everyone knows WCY knows sword, but what is he famous for? Deep internals. When the Greats all mention WCY, they make no mention of spectacular sword level, instead they praise his internal art. In the tomb, WCY wrote to the already dead LCY that LCY only broke the weakest of QZ's art (fist, palm, sword, etc), not including internal.
Btw, about YG's knowledge. I personally think he may have surpassed LHC in DGQB's theory. First, as mentioned, in the fall, he was able to learn the most efficient and smoothest attacks without the "extras" within. Second, he was gradually understanding the formless stage at 18 and probably just expanded upon it when he saw DGQB's swords. This case was first when he tried to mix and combine all the best parts from each master he learned from when he was helping to recover JLFW. Personally, I don't feel like explaining it, but Lev once gave a good explanation
