The spout and showerhead are both open to the atmosphere, meaning that when the valve is on the water could travel either out the spout or up through the shower head. Because the spout is a shorter distance and at a lower elevation than the showerhead, water takes the path of least resistance out through the spout. When you pull up on the slider, the cup blocks the water from going to the spout, so the only way to go is through the showerhead. The pressure of the water holds the cup in place. The hole was possibly this manufacturer's method of relieving the pressure in the riser when the valve is off allowing the diverter slider to return to open.

Complete Guide to Shower Diverters: Types, Functions, and Installation Tips
April 16, 2025 - This flexibility gives users the ability to combine shower experiences—for example, running an overhead rain shower with body sprays or switching between a handheld sprayer and a standard showerhead. A six-way diverter is typically operated by a single rotating control with clearly notched positions for each setting. Just like the two-way diverter, it must be used in combination with a pressure-balance or thermostatic mixing valve, as it does not regulate water temperature or pressure on its own.

r/Plumbing on Reddit: How does a tub diverter spout send water up to the shower?
December 11, 2022 -
How does it work? The slider rides very loosely. The slider has a recess that captures a rubber "cup" the cup has a hole in it. Why does the slider and cup get pulled against the spout bulkhead rather than be pushed away? Is there a moving part in the rough-in that moves and directs water up to the shower when I pull up the diverter handle.
My spout was letting too much water dribble/leak out when the slider was up and water was diverted up to the shower. My repair was to place an o-ring inside the cup. The spout still dribbles, but much less.

I basically have the same question. I get to take a closer look at the gate. It sits very loosely when it is supposed to be closed. The gap is still pretty wide. I wonder if it is the way it should be. Or the previous house owner found the wrong part to repair. Let me know if you get more information over the last three years and have the answer now.
