When it comes to technology, multi-tasking is completely different.

For iOS, some "multi-tasking" features include "switch between apps by double clicking the home button and selecting a recent app", and split view.

Windows considers "window snapping" to be a multi-tasking feature.

As we all know, multi-tasking isn't really thinking about two things at the same time, it's switching between those two things very rapidly. When it comes to technology, you can hardcore multi-task by having 5 video chats going while watching a youtube tutorial and writing your grocery list (which is more along the lines of the study you linked), or else you "multi-task" by having plenty of windows open in a larger viewing area to lessen the need to constantly switch between apps.

e.g. As a web developer, I would not be productive without switching between code, terminal, and chrome.
