It's only a confusing comment if you're a dolt. Morrissey has been on a relentless mission to rewrite his personal history ever since the court case happened, and his lies and delusional nonsense have only been exacerbated as he's aged.
To be able to weather the loss of The Smiths (no doubt an extremely taxing event, emotionally) while at the same time immediately moving forward, taking no time to mourn, NOT giving up, and then within a few months coming up with two albums' worth of some of his best ever work, well...that doesn't seem very "zombie"-like to me. It seems driven and focused and creative and alive...traits he has lost by the truckload ever since he lost the court case, and especially since the 2004 comeback-fervor died down.
But looking back, as he is, in bitterness on the joke that his career became, and all the things he's done to sabotage himself and his legacy, then yes, I'm sure he finds it very easy to just claim he was not in his right mind when the solo thing got started.
But the albums and the artifacts say otherwise, if you look beneath his spin.
