Weird tense combination. I'm not sure if it's officially wrong but it feels weird to change tense mid-sentence after so many words. "X will do ABCDEFGHIJKLMNOPQRSTUVWXY and does Z." I thought it could be a typo for "X will do ... and do Z" but only when I went to write why it's weird, I realised it doesn't have to be a typo. It doesn't even matter here. It would mean the same thing either way.
