Chainsaw chain spins after start until I hit the throttle

Question

Immediately after I start my chainsaw (Craftsman 358.350280), without holding the throttle, the chain moves fast. As soon as I press and release the throttle, it comes down to idle fine and the chain stops moving. Is this expected? It seems unsafe/I would think the chain wouldn't move until I hit the throttle.

Reading the online operation manual for that model product, I found the following:
Starting a warm engine

Pull the choke/fast idle lever out to the full extent, then push the
lever back in completely (to the OFF Choke position)
Slowly press primer bulb 6 times.
Pull the starter rope quickly with your right hand until the
engine starts.
Squeeze and release throttle trigger, allowing engine to idle.

This sequence of events, particularly the last line, implies that the starting sequence is performing as you describe and as expected.
