In addition to the display's aspect ratio, the resolution also plays a role in enabling this feature. The Pixel 9 Pro Fold's display is expected to have a resolution of 2,076 x 2,152 in portrait mode, which necessitates the left-right split option for optimal multitasking.

It's worth noting that split-screen multitasking isn't entirely new to Android. It was first introduced in Android 7.0 Nougat back in 2016. However, the implementation on the Pixel 9 Pro Fold, with its unique aspect ratio and resolution, represents a significant step forward in making multitasking more intuitive and efficient on mobile devices.
As the Pixel 9 Pro Fold's launch date of August 13th approaches, it remains to be seen if Google has any other surprises in store for multitasking enthusiasts. While the focus of these updates has been on the Pixel 9 Pro Fold, the benefits extend to other foldable devices as well. As the foldable market continues to grow, features like left-right split-screen multitasking in portrait mode will become increasingly important for maximizing the potential of these devices.
