Only watched part of the video but what you are pointing to is a potato leaf (Pl) plant. As you said, most tomato plants have the other kind of leaves and they are referred to as "REGULAR leaf" (RL)
However, Black Krim is not supposed to have PL. Genetically speaking, PL is a recessive trait so it's pretty far off the genetic norm.
Did you sow any seeds for a variety with potato leaf foliage? It could be a mix up on your part, or stray seed from the company, which can happen.
