Yes it is obfuscation! And it even caught me and I noticed it.
Unfortunately, I accidentally sent out a post criticizing guy two's
position (it was written before I caught my error, but was accidentally
sent!). But guy two's statement is totally correct. Guy two has a
history of using obfuscation like this so that he doesn't have to say,
"You are right. I agree with you." Guy two likes to keep things alive.
But Guy two isn't totally correct. The voltage on a line varies
regardless of the SWR, not just when the SWR is less than perfect.
