I mean, is there some other feng shui reason for not having across from each other?

Yes. An effective kitchen design is based on the work triangle.

Now, although there are configurations that follow the work triangle methodology that include having the sink and stove across from eachother, this requires a complete 180-degree turn when moving from one to the other. Other configurations that require less than 180-degree turns are significantly more efficient, and are truer to the goal of the work triangle of creating a useful efficient space.
