is this site's time control for real???

i played a horde chess game with Fischer time control of 1 hour for the whole game zero increment and my opponent run out of time for about 40 moves in a row but he didn't lose.

when his time run out his clock shown 0 mins or -0 mins but this continued happening all the time and he never lost on time. he had time problems from the beginning and i adapted my play to play lower quality moves for gaining time and putting time pressure on him.

that didn't work since he can lose by time running out it seems. go figure.

i saw this site as a good chance to escape from all the chess i was playing with all these variants but its great flaw in time control disappointed me.

my opponent finally lost on time as it seems and see this moment i'm writing this.
