Judging from pure logic, not from testing in code:

Do I see that right, that in the end this code should be executed in the parent-theme? But the parent theme is not loaded, while the child theme is looking for the parent. So this class/action should never be fired.

Alright. This code snippet works* and we are currently shipping it with our theme.

Works is relative here, because if you do not have the parent theme active (but the -premium version installed), the child theme will be shown to have no parent theme. This might throw off some users, but that is certainly catchable in support.
