I think the way to look at your question is to consider what you would do if the orange bag did not exist.

If the fielder is touching part of the white bag and part of her foot is in foul territory, would you give her the out? Of course you would.

Now put the safety base next to the white base. Does this limit the area where the fielder can have her foot? I.e., can she still have her foot partly on the white bag and partly hanging off into foul territory, even if that part of foul territory is covered by a safety bag? I would say yes.
