Nope its not, like the Soulflyer breathing from another higband issue i like to hear the rulemaster on that, the Rulebook paragraph there wasnt suffiecent either

.
BTW how does the Totem 3 grap and hurl attacks (stated as natural attacks) but it needs two actions to do it? Can it make 3 attacks in the first action than? (all three kinds) and than only 2 next two? So much questions, your little paragraph dont covers

I just read through my version of the rulebook and it states:
That the Totem "has" a Tusk attack, Natural Weapon .... -> agreed on
The other two attacks both start like:
It "may" sweep and it "may" spend 2 actions to grap and hurl .....
It dont states it "has" this attacks it says it may decide to use the other two forms of its natrual attack instead off the tusk one.
Just my two cents after reading the wording of the rules.
