Yeah, it's intended.
You can access either the collector or express lanes from the Lougheed onramp.

Options B and C have eastbound onramps to Hwy 1.

So Option A is probably designed to reduce volume on the overpass through the interchange
- i.e. it's not much different that what exists now, so they need to reduce volume to avoid gridlock on the overpass.

Whereas Options B and C have a lot more redundancy (even though they have more traffic lights), so it can allow more movements.
