I've used Maya a fair bit, but I've only just started working with the API and the Node side of things. Before this I've mainly used it for modelling and UV'ing. Though I've also used Houdini a bunch so I am familiar with Node based workflows. With your example of the 'inputGeometry' attribute, from what I've read from the documentation (the specific page I'm referring to is linked below) it seems like instead of using Logical Indexes 12, 13, and 26 to access those three plugs, I could simply use Physical Indexes of 0, 1, and 2 instead. From what you're saying I'm guessing this is incorrect, but I'm not sure why. Would you be able to expand on the iterator explanation please? I don't quite understand it.
