My Rhodo is Confused

My spring blooming Rhodo has popped a bud and is blooming proudly.  It's the only one on the tree that is blooming - all the other buds have not opened. I googled, and it tells me that the buds that have opened in the fall will not open and flower again in the spring; but those that have not opened will bloom in spring.  This bud should be proud of itself.  It was the smartest bud -  thinking this mild weather, with a nice  mix of sun and rain, might be spring.  Bloom baby, bloom.!! Thanks for taking a chance!!
