Interesting read, seems it was different according to prevailing doctrines at the time
I find the discussion around the centurions on the edges - thinking how it could afford better mobility, situational awareness and adaptability without throwing the formation too much out of step if legions were required to lock shields and when charging was required allowed the centurion enough space to lead it if necessary
Good question. This still leaves questions but I found it interesting.
