The cheesesteak I got used white American cheese why?

I worked at an Arby's for two days. I quit when I realized their day old meat that didn't sell was mixed into the meat the following day. Watch the color of the meat, if you get slices that are different colors of each other, that's your tip off. The other is if they drown the damn thing in sauce. 

Cool story and all, but was it actually unsafe?

It can be.

When food is "carried over", the basic rule of thumb is that it should be the first food to be served. Sometimes, this isn't possible due to the nature of the food since the texture or flavor might change due to the age or refrigeration or both.  So a lot of fast food joints will blend the old food with a fresh batch to mask the changes. Homogeneous mixtures like ground beef (not patties) or pancake batter are great candidates for this for obvious reasons.

What's supposed to happen is that the food handler is supposed to ensure that that "blended" batch is to be used completely up and not blended into the next batch. The Arby's I was at didn't do this. Each batch was blended into the next throughout the day. When a particular batch was deemed "too old" it was sauced to mask the age. Then this was further blended into each succeeding sauced batch.

It should be obvious by now that if any batch at any time was tainted, then every succeeding batch afterwards becomes tainted.

Most restaurants that handle homogeneous mixtures have clear cut policies in place to prevent blending old with new except for the very first batch. If Arby's had any sort of policy like that, it wasn't followed through by management or staff at the one I worked at.
