I'm not even sure that's what he wants, but there's certainly no reason to be playing Scott Wedgewood as the back-up instead of him.
The reasons to play Scott Wedgewood as Preds back-up instead of Askarov:
1) Askarov isn't any better than Wedgewood right now (probably - or if he is, he could beat out Wedgewood in training camp if he really showed it)
2) Gets Askarov 60 games in the AHL instead of 20 in the NHL
3) Askarov gets more time to work with Mitch Korn on refining his goaltending technique
3a) Learning how to position his arms
3b) Learning how to stay square to shooters and not lose his posts all the time like he does
3c) Learning to hold onto his stick
3d) Learning to stay calm and focused
3e) Working on his mental preparation and consistency
I don't think this holdout stunt bodes well for Askarov's NHL future. He wants to rush into an NHL job? It means he doesn't really believe that he has a lot of work to do. And if he doesn't want to put in that work now, he's going to have a tougher time reaching his full potential. Maybe for a little while he'll be able to get by in the NHL just with his fast legs and flexibility, but eventually he's going to need more than just relying on those freakish skills. If he would just invest that year of additional study and apply himself, it would be far better for his future, and that's what the Predators were setting up for him by signing Wedgewood.
