I believe there's a mistake in this sentence. The last part should be "they are like two peas in a pod" and not "they are like AS two peas in a pod". Is it possible to have it corrected? It could confuse other learners. Thanks

Thank you for the correction, Jessie. The idiom is indeed 'to be like two peas in a pod'. A less common variant is 'to be as like as two peas in a pod', which is perhaps what was meant here.

The expression "be like as two peas in a pod" is a valid one.
However, I would agree that it isn't used nearly as much as "be like two peas in a pod".
