I was always told to mix that kind of thing up, because while doing the push lifts, you are stretching your pull muscles, and lifting with the pull muscles, you are stretching the push muscles...and they kind of offset each other, If it were me, I would split it more like an upper body 1 day, lower body thing another thing...although I am new to this and I am probably wrong....please nobody bitch me out and through a little pissy fit if I am wrong.
