The window was the whole design
The room started as most primary bathrooms of its era did: an oak vanity, a tub-shower against the wall, and beige tile everywhere. It also had a window with a view, and almost nothing in the room was arranged to use it.
So the layout was rebuilt around that opening. The freestanding tub sits under it, the shower moved to the wall that has no view to lose, and the vanity took the opposite side. The window did not move — everything else did.
That is usually the cheaper decision as well. Moving a window means structural work and a permit revision; moving a tub means moving a drain.
