TipTap left with 2 fingers fixed on trackpad

I assigned the 2 fingers fixed tiptap left gesture to window switcher on my Magic Mouse, plus made a named trigger with "return" on fingers up to mimic the default "Activate Selected After Releasing
Modifier Keys" action.

Works flawlessly on my Magic Mouse but when I make the same gesture for trackpad, it doesn't let me repeat the gesture to navigate through the switcher and performs a "return" action right after make a second tiptap. I use my index and two fingers on its right for this gesture. However, when I use my thumb instead of index, I can navigate the switcher with no problem and "return" action only runs when all fingers are released.
