Range on surging totem?

Back when we had windfury totems I used to just have totemic projection macroed with stormstrike so my totem would followe me without me thinking about it … however … with this totem it seems to have a smaller radius in which the tremor happens … it says 40 yards but I think that’s the “placement” range.

With windfury totem it didn’t matter because as long as you’re in range you get the buff.

Is the range also 40 yards or is it like 12 for the totems ability?
