They attempt to address the L-1A & B visa path on the right side where they ask "Working on H1, L1, etc". Admittedly, the chart doesn't include the extra step of having to qualify for an L-1. At least for the L-1A, you'd need to have worked for a subsidiary for 1 year before being granted the visa. The good news is that once you have the L1, then you can follow the EB1 or EB2 paths on the far left hand side.
