Running a different cached node based off a condition

I’m looking at the Survival Game example project (A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums)

In their animation blueprint, they run one of 2 blendspaces depending on whether a flag is being set. For the life of me, I cannot work out how the blueprint is determining which to run. I have attached a screenshot to illustrate.

From what I can see, there are no condition variables on the “Use cached pose” nodes. So how does the animation blueprint know which one to run through?

Sorry that my terminology is off, I’m new to the animation blueprint so I can’t articulate as well as I’d

like.
