Yes and no.  It depends.

If the compiled code complexity raises above a certain threshold, the LabVIEW compiler will be forced to suspend certain optimisations.  This can happen by widespread usage of inlined VIs for example. Problematic is that the "displayed" Code complexity for such a VI will seem small, but the compiler, when extracting the inlined code will soon hit a barrier and start limitinf compiler optimisations. If the magic pattern of unbundle-bundle happens to be affected, you will see some big differences between those two pieces of code. The IPE will ALWAYS be in-place. The unbundle-bundle will NEARLY ALWAYS be in-place.  Be aware of the differences.

So when do I want to use the swap values function?

Very rarely, and mostly when you want to actually swap two values. If you're leaving one output unwired, you probably don't need it.

This function is a relatively recent addition to LabVIEW to improve performance in a few unusual cases, for example I've seen sample code that uses it to implement recursive data structures (such as a linked list) efficiently.
