Congrats to Dortmund for beating the worst teams of the season 2 times in a row! 
Until they face more challenging teams, it is difficult to be sure whether they are back on track or not.
Before anything else, they face Lille in the Champions League next time. It is a home game. I think Dortmund will get a good result to get advantageous.
Interestingly they seem better there compared to the Bundesliga...
Even though Borussia Dortmund is not going to win this trophy this season, they have proven to people in three games now that they are improving because they beaten those three teams people thought that Borussia Dortmund will not going to win those games to improve their points but they prove them wrong. I guess Borussia Dortmund is coming back to good performance because their players are not struggle to score goals these days compared to the beginning of this Germany league game were many teams use to take advantage of their weak to disgrace them with many goals to beat Borussia Dortmund.
