As far as I can tell Volker Gerloff is a real lawyer (website, facebook looks good at first glance, website links to facebook page). He writes on facebook:
Das BAMF schafft es immer wieder, zu verblüffen. Mein Mandant ist Afghane und es ist unstreitig, dass ihm in Afghanistan Blutrache nach paschtunischem "Gewohnheitsrecht" droht. Die Ablehnung wird nun u.a. damit begründet, dass nach diesem "Gewohnheitsrecht" nicht zwingend die Tötung des Mandanten erfolgen muss - es genügte auch die Übergabe zweier heiratsfähiger Mädchen aus der Familie des Mandanten an die Familie, die auf Rache sinnt. Ich bin gespannt, ob das BAMF noch mitteilt, woher mein Mandant die beiden Mädchen zaubern soll und ob das BAMF dann die "Übergabe" organisieren würde(?). Es läuft gerade vieles sehr sehr schräg!
update (Wortlaut der BAMF-Entscheiderin im Bescheid): "Als Kompensationsmöglichkeit wird auch aufgezeigt, dass etwa zwei Mädchen im heiratsfähigen Alter an die Gruppe des Opfers übergeben werden könnten, ohne dafür eine Brautgabe zu erhalten." [...] "Die Tötung des Ausländers ist also nicht der einzige Ausweg, die Streitigkeiten der Familien beizulegen. So ist es nach paschtunischem Gewohnheitsrecht vorstellbar ... dass zwei Frauen aus der Täterfamilie an die Opferfamilie übergeben werden.".
Paraphrased: BAMF (German asylum government agency) supposedly denied asylum to an Afghan while admitting that people would be trying to kill him, because customs would allow him to settle the feud without being killed, for example by giving two of his daughters to his enemy [for marriage]. It seems like he doesn't have two daughters. There seem to some other reasons for the denial too which are omitted.
Rough translation:
The BAMF always manages to amaze. My client is an Afghan and it is undisputed that in Afghanistan he is threatened by blood revenge according to Pashtun "customary law". Justification of the rejection includes among other reasons [see note 3] the fact that according to this "customary law" the killing of the client is not the only solution - it is also sufficient to hand over two marriageable girls from the family of the client to the family which seeks revenge. I'm curious if the BAMF is going to tell me where my client is supposed to conjure up the two girls and if the BAMF would then organize the "hand over" (?). A lot of very very weird is going on just now!
update (Wording of the BAMF decision maker in the decision): "It is shown that as means of compensation there is also [see note 1] the possibility that for example two girls of marriageable age could be handed over to the group of the victim, without receiving a bridal gift." [...] "The killing of the foreigner is therefore not the only way to settle the disputes of the families as [see note 2] it is imaginable according to Pashtun customary law ... that two women from the perpetrator family are handed over to the victim family.".
Note 1: That "also" is ambiguous in the original and could be meaningless syntactical sugar, or be a reference to other means of compensation.
Note 2: That causal "as" is what the German text implies, but doesn't explicitly say. It could just be an unfortunate phrasing in theory.
Note 3: "among other reasons" is much less prominent in the original, consisting of just an "u.a." which could grammatically be omitted to remove the other reasons.
Relevancy: A German blog with a large audience linked to it (fefe) and there are some results on Twitter for it.
I think something must be wrong about this, but can't tell myself.
