You’re allowed to stand on an extension of the line of putt after the stroke, so it’s permissible to walk in behind a ball after it has started rolling.

At the moment the player begins to take his stance, the caddie must not deliberately stand directly behind the player. The penalty is two strokes in stroke play. There is one exception which applies only on the Putting Green. Provided the player backs away and starts again on the Putting Green, there is no penalty.

Current Rule: Under Rule 16-1a, when a player’s ball is on the putting green: ➢ The player is generally prohibited from touching his or her line of putt. ➢ But there are seven exceptions (such as when removing loose impediments or movable obstructions, when lifting or replacing a ball, when repairing ball marks, etc.).

Play the ball as it lies. Don’t move, bend, or break anything growing or fixed, except in fairly taking your stance or swing. Don’t press anything down. You may lift natural objects not fixed or growing, except in a water hazard or bunker.
