You forgot to also emphasize the "SOMETIMES." It is not ALWAYS. And the Actual Reasons for it - "To enhance the Passion or Terror of the Moment."
It is not a REQUIREMENT.

The
sometimes goes for the firste part of the sentence:
1)
Sometimes the transfer of a token amount of physical material takes place
Then they give 2 examples:
2) such as blood for a vampire
3) or flesh for a wendigo
And then the first part of the sentence continues:
4) though this usually serves to enhance the passion or terror of the moment.
You can't move the "sometimes" to wherever you think it should be, just to prove your point.
Vampires need blood to drain blood for their Essence Drain to work.
Wendigos need metahuman flesh for their Essence rain to work.
And somtimes if works the same for other creatures.
So it would be natural, and make sense, to link the Essence Drain power to the dietary requirement if the creature has one.
