Technically, yes, but you'll probably miss the mark if you try to view them this way. Instead, you should see each Signpost as the source of conflict for that act of that throughline. Looking at them as a goal might be valid for some stories, but not every story will be amenable to this lens.
For example, if your story has an Objective/Overall Story Signpost #1 of Becoming, then the characters might have a goal of transformation. However, it might also mean that the characters are suddenly and randomly turning into creatures of the night (werewolves, vampires, etc...), causing them to blame someone or fight others because of it. For some, maybe it makes it more difficult to find a job, others perhaps are no longer able to get a girlfriend. The important part is that these issues trace back to their Becoming, and that it is this transformation that leads to their conflict or turmoil.
Now, I suspect that one could hardly say that "suddenly and randomly turning into creatures of the night" would be a goal, but that is meant to be the source of conflict in the paragraph above.
