I know I've heard or seen interviews where both Jon and Richie have said they wrote songs for Skid Row. We also know they were never credited on their albums. It was rumored that Jon and Richie were ghostwriting for them (and also for Gorky Park) way back when. Considering that the deal was over publishing rights which songwriters keep, I tend to believe that Jon and Richie wrote songs for Skid Row and that was their way of keeping the profits that they would have gotten if credited anyway. But that's just what I think is logical. This is one of those things we'll probably never know the real details about.
