It's my understanding that the old E2R had shifted from cut glass RP towards a more generic BBC (although not lerped all the way to Jafaican, or even MLE)?
German dialect variance is probably closer to standard english vs irish english (in which "a ride" may be an action but may also refer to animate objects, specifically an attractive person, and furthermore even borrows some grammatical constructions from the gaelic)? Compare the range between SAE vs AAVE.
EDIT: https://www.youtube.com/watch?v=9J9dRmnlWJY is an example of the same interviewer employing a broader (too far east for my ear to place) dialect; presumably in the AML interview he had also been accommodating by hewing closer to swiss standard german.
EDIT2: and for https://www.youtube.com/watch?v=ogpYWKpYVaw&t=40s (with an eastern german singer) he starts in dialect for the introduction to his audience, but then immediately switches to a very standard german for the interview qs posed to her.
