SUMMARY
I was trying to assign more than one key bind to the task switcher, like walking through all/current windows forward/backward. But I found:

Keybindings in "Shortcut" menu only activates the switcher, it's the keybindings in Task Switcher menu that tells the switcher to walk forward/backward.
The keybinding setting in "Task Switcher" menu doesn't allow multiple bindings. Pressing "Meta+Tab then Meta+J" will assign a keystroke combo to it, not 2 bindings.
Also, assigning keybinding in Task Switcher menu will assign a keybinding in Shortcut menu and vice versa.
So what's the point of making 2 separate shortcut menus anyways? Why not just use a single one? To me it's kinda like sacrificing the ability of assigning multiple bindings to gain the ability of assigning a combo.

So I think it would be better if:
1. Remove the settings in Task Switcher menu and make the switcher solely rely on the bindings in Shortcut menu
2. Or, let the settings in 2 menus share a same set of settings: user can assign multiple bindings in Task Switcher menu, all changes in Task Switcher menu will affect Shortcut menu too and vice versa, since they share a same set of settings. This will ofc remove the ability of assigning a keystroke combo (but who uses a combo to hop through windows??)

STEPS TO REPRODUCE
1. Clear Walk Through Windows and Walk Through Windows (Reverse) in Shortcut menu
2. Assign Meta+Tab and Meta+J to Walk Through Windows in Shortcut menu

OBSERVED RESULT
Only Meta+J is automatically assigned in Task Switcher menu as "Forward"
Pressing Meta+Tab will only activate the switcher, pressing it twice has no effect.
Pressing Meta+J will activate the switcher, pressing it twice makes the switcher walks forward.

The issue that you can set additional keybindings in System Settings > Shortcuts that do not work properly is being tracked in bug 492958. I'm marking this as a duplicate of that.

Removing the Keyboard shortcut configuration from the Task Switcher configuration page does not make sense to me, as that's where you configure task switchers, so users would likely expect it to be there. It's similar to how the Plasma keyboard layout switching shortcuts are in both the Keyboard configuration module and in Shortcuts - having some of the switching options available in one place, but not the keyboard shortcuts seems unnecessarily cumbersome.

It's also the only one that currently works properly. Once the task switchers can handle more than one shortcut, it would likely make sense to expand the Task Switcher configuration module to allow more than one shortcut to be set.
