I'd say that was a bad call given the fact that is quite easy for a veteran to make credits when starting over.
But the fact is: it is possible to have the same account, at least for xbox/pc. There was a case here on the forums (quite recently) when someone could start on pc using the xbox account and, for a brief period of time, could play on pc using the commander on xbox.
It happened during an account transfer XB -> PC and FD "corrected" this and claimed it to be a bug. It ended up with the cmdr on xbox being deleted.
Didn't see that one. Presumably broke the terms of some contract rather than being technically un-feasible.
