On Mac swaps the contents of two files:

The ExchangeFilesMBS function allows programs to implement a "safe save" operation by creating and writing a complete new file and swapping the contents. An folderitem, alias, FSSpec, or FSRef that refers to the old file will now access the new data. The corresponding information in in-memory data structures are also exchanged.

Either or both files may have open access paths. After the exchange, the access path will refer to the opposite file's data (that is, to the same data it originally referred, which is now part of the other file).

On Windows files are renamed so they exchange their paths.

PS: Real Studio does not notice the change, so the folderitems you pass should no longer be used. To access the file, please make new folderitem with parent.truechild(filename).
