Wide guard does not fail after using it so many times?

Question

I saw it twice during the rating battle today as my opponent used wide guard more than 6 times without fail. Is it bug?

Answer 1

This is not a glitch, nor is it rare. As of XY, the Guard moves can be used consecutively without risking failure at any time. They do however decrease the chance of the Protect moves working.
