More like pure confusion. I don't mind a temporary reproduction method for a young queen before she is able to lay eggs but it needs some drawbacks, making the egg laying more efficient in the end. Eggmorphing would have been better.
Alien is full of rape and mother imagery. Having a young queen face rape a human mother and "replace" her baby with its own is alien like and f**ked up. But skipping over the egg/facehugger and the multiple chestbursters makes it too overpowered and an asspull. It was a plot device to increase aliens numbers quickly.
