Possible puzzle bug #4273

In this puzzle: http://en.lichess.org/training/4273

Wouldn't this also be a solution? http://en.lichess.org/8AecM3Ul

In both cases, you are left with queen against rook.

yes of course it's a solution, but in the first case, it;s a bit more stronger, as u get ur opponent king in the first rank and u don't lose the d pawn , still,I agree both solutions are nearly same
