I have been caught the exact same way before. Don't reach for the kick!!!
You're not the only one brother! Made that mistake myself trying to block what looked like a front kick only to catch the crescent kick across the face.
He took his time and set it up right. He threw the low straight back kick first to get him thinking back kick and then through the spinning heel so when the other guy blocked low, nobody was home. DING! Cancel Christmas, lights out!
