are you sure about that? the king could have moved back up, but in front.. moved from right side to left side between those two lines, without moving in front of the queen line.
If Anand played the king to the eighth rank instead of to h6, Carlsen would have kept checking on the seventh and eighth ranks, with a draw by perpetual check.
When you assume that a world-class GM played "purposedly" for a draw that would lose him the championship title, you're probably wrong.
> He took queen with queen, clearly
He was in check. Taking W's queen was the only way to avoid losing his own for nothing.
