Quick ScrOG Question with AK-47

Hey everyone.
I am about to start a ScrOG Setup with Serious Seeds Ak-47. The AK is supposed to grow up to 95cm-100cm fully grown. If I top these plants when they are around 6 inches, shouldn't these plants use more energy on the two new shoots thus making the new shoots not grow as high as if you didn't top? I just need to know this because I am trying to design the direction I want the shoots to grow without the tops getting too far from the center of my tent.
Thanks

Short answer, yes.
Is a matter oh how long you veg though, You can veg it to 10ft tall before flower... So them saying thats what the plant finishes at is off... I never understood why they do that. They should have a description for how much a particular strain stretches.
