"call to arms" doesnt alternate warcries after 1st sequence (it alternates on 1st)

title

+1 why would it start a sequence then block itself on the 2nd warcry forever, I hoped that I could have at least call to arms support alternate between two warcries even if they shared cooldown to exert my slam with 2 warcries.
But it does not and only use the 2nd warcry in the linked gems after having done the first cycle.
