There is 0 reason for Böhm to be hanging on Kerken at that point. OMG immediately goes to congratulate Hözel/AAD, who he clearly likes a lot. A little later he says:
Translated: That was so easy… you can’t even manage a sprint… haha.OMG Berlin(14:51): das war so einfach...ihr bekommt ja nicht mal nen Sprint hin ....hh
Pretty clear to me that he knew he had no chance and just wanted to gift his friend AAD here and then laugh at me after. He had literally 0 reason to not follow Hözel, besides gifting him the stage.
Edit: As Dreizehn put it in spectator chat:
Dreizehn(14:44): As if he wants to gift it to aad
Dreizehn(14:43): Stupid hanging of OMG in sprint
