Great looking Phal, it's certainly not unknown for them to have a second bloom cycle if there was a 'bump' in the weather at some point eg. if it was hot, cooled off for a while then warmed up again. That could inspire the plant to put up a new bloom.
Just a repeat (I know, I know) of my nice B. Yellow Bird with the two color variations on it at the same time. I'm just always delighted with this plant that changes colors so much.
