No, lol, I mean, when you abuse your ID / SID for a shiny spread, there's a possibility that the PID (PID determines shininess, ability, gender, nature) that you abuse for will also be shiny for a different nature. So when I abuse my ID / SID for the shiny Modest spread, that means I'll also have a shiny Timid spread. Meaning I can catch shiny Modest pokemon, and shiny Timid pokemon.
I'll be catching the Zapdos as Modest, since that's what you're requesting :D
Does that make sense? Lol.
