The five attitudes are: Upper, Middle, Lower, Right Side, and Left Side. These are the five. Although attitude has these five dimensions, the one purpose of all of them is to cut the enemy. There are none but these five attitudes.
The five kinds of guard are the upper position, middle position, lower position, right-hand guard, and left-hand guard. Although the guard may be divided into five kinds, all of them are for the purpose of killing people. There are no other kinds of guards besides these five.
The five guard positions are the high, middle, low, and those of the two sides, left and right. Five guards can be distinguished, but all of them have as their goal to slash the opponent. There is no guard position other than those five.
I would also be a bit doubtful about Hasso gamae being able to cut from 8 directions. Hidari gyaku kesa and Hidari dogiri seem to me to be a bit impractical from migi hasso gamae. But perhaps I'm just not good enough.
