To understate the obvious, Paul Levesque has a unique position in WWE. He's the son-in-law of the owner, married to the boss's daughter, he's a stockholder, he's got major say in storylines.
For these reasons, in his role as Triple H, he has no current standing as a performer to protect. Personally, I'm a little disappointed he's not a full-time wrestler anymore; he certainly seems healthy and in-shape enough to be. But he's the 800-pound gorilla who can sit anywhere he damn well pleases. When an opponent or plot-line shows up that calls for a hero with true star power, he steps into the ring.
This is the path he's chosen. He'll perform a couple of times a year as a wrestler, doing some promos leading up to the event, giving his usual maximum effort during the PPV......then marching back to the front office to his managerial job. Except for the front office part, Triple H's function these days isn't much different than Brock Lesnar's. Trips is like a gun for hire, except he doesn't have to be brought in; he's already there.
Paul Levesque isn't Brock, Rock or Mr. Socko; he's staying. Length of contract doesn't matter, nor do continuing storylines. When WWE needs a true superstar to work a special program, Triple H will step up to the plate. Whether he announces his retirement or not after his loss to Brock, he'll still wind up doing what he's been doing the past couple of years. As much as he may insist he'll never get in the ring again.....he will. Somewhere along the way, some ultra-bad guy will perform a dastardly deed and an outraged Paul Levesque will duck into a phone booth, change into his fighting gear and emerge as.....Triple H! {cue heroic theme song}
And you think John Cena is depicted as Superman?
