Basically this is something the body cannot do. The fat is stored with some glycerides that can be converted to glucose but the rest cannot.
So this theory sounds like broscience to me.
What you are actually doing may work though, 10 minutes of HIIT will not burn much glucose (this is good—if you burn glucose it has to be replaced—you want to burn fat) and will add a fair bit of fat-burning muscle.
