this is NOT true, the stronger your stance is, the better it is for blocking, because if your opponent uses a stronger stance there is a chance he knocks your saber away making you unable to block a follow up attack.
Also, there are some not blockable attacks, like backstab, backslash and DFA. Also red swings are not fully blockable, they will always do a small ammount of damage.
You will never be able to block everything just standing still, you need to take evasive action, try to predict your opponents next move, and start a counter move, or get out of his sabers way
