Note that you can do this with "dragging > without drag lock" too: when tapping twice, just keep holding your finder down and then drag.

I personally find this much easier to use, compared to the "three finger drag". But to each their own of course.

Also, if i remember correctly, the three finger drag interferes with some other trackpad gesture related to app expose or something like that.
