My Plants Are Cloning Themselves Via Roots?

I got a sativa clone from my buddy and have her in the budding state atm. When I got her I put it in fresh soil, never had a male or seeds anywhere near it. About 2 weeks in to budding I noticed another cannabis sprout. Ive read about a phenomenon where the root of a plant decides to grow towards the surface and sprout instead of following the rest of the roots. I dug up this sprout and confirmed it was grown fully out of an attached root to the main plant. I put this new sprout in to another pot by itself , again in new, untouched fresh soil. This sprout has turned roughly 2 months today and is thriving 10x more than its original. But thats not the point, now out of this sprout I separated, anoooooother sprout has begun to emerge from the soil, again fully grown out from the roots of its predecessor. I now have 3 plants instead of 3. Whats goin on maaan? 

 

I will definitely grab a picture with the roots still in tact once the new sprout is mature enough to transfer.

I know that this isnt unheard of, but I heard of the chances of it happenening once are already one in a million, so to have it happen twice simultaneously, there's gotta be something more behind it, mutated genetics or sooomething.

 

ill be back in a couple weeks with pictures once the spout is mature enough to transfer
