22awg =0.326 mm^2

The passive power injectors use pairs of conductors for sending power and ground (a total of four conductors used).
24awg = 0.205 mm^2
So you effectively you have 0.410 mm^2 cross sectional area of copper which exceeds the 22awg requirement.

At least that's how I was planning on explaining it away if the question came up.
