Actually if you are inside of 10 m and your trailing foot steps forward of your lie before you establish your balance after putting, then it is a foot fault.
There were a couple putts that looked like his trailing foot would have landed in front of his lie if we could see his feet. But since we can't, for all we know his trailing foot landed to the left of his mini which would be ok.
