Yes Bryson has it right!

Bryson’s putting stroke should be emulated regardless of the length of the putter with this in mind. The ball position sits under the fulcrum point of the lever system , left armpit , right armpit in context. That is the lowest point in your stroke pattern . It should , could result in better roll , less skid and bounce as the putter is neither going down nor up in its arc. Try it ! Coincidentally I posted and referenced this exact topic last week @kamgolf on Instagram! Good luck!
