When striking these pillars on Nord Town, it is typical that they make the sound of their straw roof rather than wood. As the video shows, they can still make the wooden sound - I'm not sure precisely how to reproduce this,but it seems that strikes which extend around to the back of the pillars (like stabs to the right, or right swings) will often achieve this - but they usually sound incorrect.
I asked somebody else to test this and they found the same thing, so it appears to be a universal issue.
