Minion Ability Question

When a Minion has a built in bonus such as the Angry Spider Bots' "Spider Webs: +1 to Hinder when making Webs" is the +1 added to the actual die roll (like a Boost) or added to the result (rolled a 1 which would make a -1 Hinder, but it becomes a -2 Hinder)?

I would assume it works the same as a Boost impacting the die roll itself, not the result. However in the Tome of the Bizarre issue the Swarm of Scarabs has the Ability "Seething Swarm: A swarm of scarabs cannot Attack, but has +1 to Hinder rolls". Does specifically calling out that the +1 is to "Hinder ROLLS" instead of just saying "+1 to Hinder" imply that these two Abilities opperate differently? Or is it just inconsistent language/terminology use? 

I think it's just inconsistent terminology; I treat both of those as a +1 to the result of the die.

In both cases, it's referring to Hinder, not penalty; Hinder is the Action, and therefore refers to the number on the die, while the Penalty is the -1/-2/etc. that results. If it said "increase the resulting penalty by -1," then it would turn a rolled 6 from a -2 penalty into a -3. But since it says it increases their Hinder, it would turn it into a 7, which is still a -2 (if I recall correctly).

It's inconsistent wording, but still clear in what it means, imo.
