Why do Swiss road border crossings differ in setup? [closed]

Having crossed the Swiss border at numerous locations by bus, I've observed that they use totally different setups.

Setup 1: at this crossing, Germany and Switzerland each has a separate one-way checkpoint, meaning a border check may be done by the country of entry, but not the country of exit.

Setup 2: at this crossing, both Switzerland and France have checkpoints in both directions, meaning you may be checked twice in both directions (which has also happened to me once)

Setup 3 (most common): this crossing has a common Swiss/German checkpoint, meaning you could theoretically be checked by each country at the same location. In practice, I've only been checked by the country of entry at this type of crossing, but don't know if it varies.

What is the reason behind the difference between the crossings?
