Warcry: Question about Totemic Heart and Fercocity

Can Totemic Heart proc Ferocity?
The Tooltip for Ferocity says it can proc once per direct Warcry use. I’m assuming that means Ferocity can’t proc itself, but Totemic heart would still be considered a direct use even though it’s a totem.
So while Totemic Heart is giving it’s 3 beats, I’m assuming Ferocity can proc within that 5 second cooldown, which results in another totem dropping.
