It's still a release of tension when it's actually confirmed. Nothing is done until his ball is in the hole.I think you may have misunderstood. The celebration on the 18th /72nd hole is totally understandable and natural. It's a sudden rush if excitement.
The celebration on the play off is more premeditated imo as he had tome to accept what was happening as it was obvious for 5 minutes he woukd win.
