So now the next layer of onion.
With push-tag/Ctrl-., if I press it once I go to the definition, and hit it a second time and it takes me to prototype.
Tried the same functionality with push-tag-filter-overloads()/Alt-Shift-., when I press it a 2nd time after being brought to my function definition, it does not bring me to the prototype, instead since cursor is at the beginning of the line it is showing me the definition of the return type of the function.
