The one you posted? He hits the ground with his putter, then walks in front of the spot he hit prior removing his putter from said spot, and it ends before he ever moves out of the way of said spot, such that it is 100% impossible for any of us to have any opinion whatsoever about the extent of the damage.
I also am assuming that the info @Valleygolfer posted is correct ... that there was enough damage done and in the line of somebody in the following group, that they had to have it repaired.
Don't mistake my previous post as any kind of defense for Poulter. ;) Of course the reaction could have been handled differently. What I'm saying is that, more importantly, Matsuyama's anger after hitting such a shitty putt could have, and should have, been handled differently, and that is more important than his potential hurt feelings.
