The 'blow hot blow cold' story often refers to someone who is inconsistent in their attitude or behavior. For example, a person might be very enthusiastic about a project one day and then completely cold towards it the next. It's like the fable where a man blows on his hands to warm them and then blows on his soup to cool it, showing his changeable nature.

It's hard to say for sure. 'Blow' could be a complete work of fiction or have some roots in reality that have been significantly transformed in the storytelling process.
