Frankly, if you don't need much help running a petitioner/granter conversation, these templates probably aren't for you. If you sometimes struggle to decide how an NPC reacts in a petitioner/granter conversation, these templates could help.
The title "conversation guide" is a little misleading. First, the document doesn't cover conversations in general. Instead, it specifically covers a petitioner/granter conversation: the petitioner wants something that the granter is potentially ready, willing, or able to do, say, or offer. The granter might or might not grant the request, and there might be enthusiasm, strings attached, or counter-offers.
Second, I'd expect something called a "guide" to have more guidance. This document offers two printable templates with a few examples filled in. That's it. There's no explanatory text beyond that. There's no guidance on persuasion techniques, personality differences, or whatever else you might expect from something called a conversation guide. Also, why are all the sample action verbs marked "X" in the examples but not in the template? It doesn't say. Why does the Capability/Interest/Control Map have three columns, when the middle column isn't labeled, and isn't used in the examples? The bottom row of the middle column is grayed out, implying a use for the middle column, but there's no explanation.
The templates are system-neutral. You might use the templates to come up with your own mechanics for handling these conversations, such as what drives a petitoner to go with an offer vs a threat, or what it takes to get a granter to respond with one answer or another.
If you're planning ahead, you could use the templates to anticipate some potential conversations between the PCs and particular NPCs. If needed, use the Capability/Interest/Control Map to identify what the NPC is ready, willing, and able to offer or threaten and what the NPC wants or needs. Or at least I suppose that's what that template is for. Review the conversation template as a checklist for different levels of response the NPC might have. You could make templates for whole categories of NPCs, such as city guards, a faction, or an organization.
The templates make no distinction between which side is a PC or an NPC. In general (I assume), you'd fill in only the NPC side of the conversation, according to whether the NPC is the petitioner or the granter.
During play, if you've prepared templates ahead of time, you could hold petitioner/granter conversations without having to think through it all on the fly. If you have to make it up on the fly anyway, the templates might serve as a quick checklist for thinking through the possibilities.
The blank templates aren't fillable PDF forms. Either you print them and fill them out by hand, or you make your own documents using the templates as inspiration.
The version 3.1 document is, as the product description says, more printer-friendly. Where the 3.0 dialog template had filled-in silhouettes for the two characters (needlessly using up more toner), the 3.1 version has facial outlines instead. As of the time I'm writing this, the preview shows the 3.1 version. The content is identical otherwise, including the example comment in which one character offers a bribe by saying "My pursue is not light."
