That’s the crucial thing I was getting wrong.
In the book it says highest wins. Successes are removed from opponent’s dispo.
What it doesn’t say (as far as I am aware), is that with multiple teams, if you are not being targeted, then rolling less than your opponent is simply a fail.
That makes a lot of sense.
Hallelujah! Thanks, Thor. I think I finally get it.
…until next time!

Awesome! 
On a slightly related note - and this may well be explained in the book - If, in my example, Team Kenzie and Team Saxon were both performing versus actions against the Snake, they would, of course team up.
Let’s say team Kenzie helps Team Saxon, so Team Saxon makes the roll.
Is it still acceptable for the snake to target team Kenzie or is it only team Saxon that is in play for this volley?
For example, if the snake beats Saxon’s roll, can it damage Kenzie instead?
Crow
Yep.
