Does anyone know why Albertsons has started carrying O Organics food (a Safeway brand)?

This may be only applicable to those of us who live in the Southwest of the States, but I’m curious if anyone knows why Albertsons has started carrying a Safeway-made and marketed brand. Here is a link to a page about it. (I know it is a Safeway brand for two reasons: 1, Safeway has been marketing this for about 3–4 years now, and still carry the brand themselves; 2, the dairy products are made by Lucerne, which is the Safeway house brand.)

It’s been bothering me, because I haven’t heard anything about Albertsons being incorporated into Safeway (or vice versa).

It could be because the Albertsons in my area are LLC stores, but I am uncertain.
