I bet he does. the problem with the slow responses after cutting the rectangle is that Emacs performs redisplay each type the user types some character. The redisplay can be very small and optimized, but it can also be much more thorough; for example, typing "M-x" typically triggers a thorough redisplay. Each time we need to perform a non-trivial redisplay, the same problem with long lines hits again.
