An interesting use of the 4004 instructions

I was looking at some disassembled 4004 code when I came across a SKIP operation. It isn't normally an instruction but If you do a JCN with all the = 0, it will do a NEVER jump. This is the equivalent of a SKIP instruction. I would suppose a JCN with = $8000 would be an always jump,
