Brake booster to KB Wildcat Manifold

Hi Guys , I noticed my brake booster vacum hose is connected to a tee coming from the back of the holley carb, also picking up the modulator for the trans. My rear manifold vacum fitting is connected to the pcv in the manifold. Trying to figure out if they got switched at one time. Should the booster line go directly to the manifold by itself ?

Thanks

 

The pcv is going from the back in the back of the manifold and connects to manifold vacum just below the back of the carb. Like you said probably no big deal , I actually have better vacum now after tuning the carb
