I don't know the answer - what is it?
As you know MS came to F1 as a Mercedes factory driver. They paid his first ride with Jordan. Mercedes kept an option on him until the beginning of 1993. In 1993 Mercedes was entering F1 with Sauber and they even issued an official statement that their drivers would be Schumacher and Wendlinger! (A pretty well-documented intent, I would say.) However by the time MS found his new home at Benetton and they were on their way up, so understandably he wasn't too keen on joining Sauber-Mercedes. He told this to Peter Sauber and Sauber was a gentleman and said: "There is no way you can force a driver to do something he doesn't want." So they simply released him from his contract with Mercedes. (Wouldn't happen in today's F1, I think.)
This however wasn't the last time Schumacher and Mercedes considered a re-union. When Michael negotiated with Ferrari in 1995, he also negotiated with McLaren-Mercedes. Why did he choose Ferrari over Mercedes? The answer is from the man himself:
“There were several conversations and meetings with McLaren-Mercedes, for example 1995 in Monte Carlo,” he said in an interview with German newspaper Suddeutsche Zeitung’s magazine.
“But I noticed that we didn’t really fit together.
“I didn’t fit to McLaren or to be honest to McLaren boss Ron Dennis.
“It seemed to work out with Mercedes I am sure we would have found a way.
“Ron Dennis and I had different ideas how a Formula 1 team should work.”

Michael's reasoning goes a bit further in explaining what those "different ideas" mean (in short he says: it's not about wanting a Nr 1 contract - according to MS he never had that -, but in his opinion once the team can see who is the faster, and who has a better shot at the title, they have to support that driver), but it's already off topic here, so I don't want to copy the whole article here.
There were also negotiations between Michael and McLaren in 1998.
As for Roebuck's answer, you can search for that in the autosport.com database. It's more just a speculation without considering these above facts and quotes from the man who knows it the best - MS.
But I don't want to discuss MS-Mercedes relations here, it's waaaaay off topic. All I want to say, in the articles I've read from Roebuck he didn't seem to me more knowledgable than any average fan. Maybe I just read the wrong articles, I don't know. He is probably more knowledgable on subjects he likes, at least I hope.
