Agreed - although I disagree with his suggestion that using a back bevel is going to create flutter whereas a high angle frog won't.
If the blade is correctly seated on the frog (you'll have shiny spots on the frog if it isn't) and you have a thick differentially hardened blade or a thick flat profile cap iron (let alone both together) you shouldn't get any vibration at all.
I certainly haven't encountered any vibration problems using a back bevelled iron in my Cliftons and it's substantially cheaper and much faster to swap out than the frog.
He also missed the fact that you can skew a standard angle plane to the direction of travel in order to achieve lower cutting angles. At the extreme 45 degrees of skew gives an effective angle in the low 20s - a good 15 degrees lower than the lowest angle you can achieve with a bevel up plane in a straight line.
