Why is 看来 in the sentence 照他的年纪看来,他显得年轻？ I'm trying to dissect this sentence on jukuu.com:


  照他的年纪看来,他显得年轻。 
  He looks young considering his age.
  (Zhào tāde niánjì kànlái, tā xiǎndé niánqīng.)



照 (zhào) I think is short for 比照 (bǐ zhào) = in contrast with
年纪 (niánjì) = age
看来 (kànlái) = seems
显得 (xiǎndé) = seems [again (!?)]
年轻 (niánqīng) = young.


I'm puzzled as to why "seems" appears twice here.  I think 他显得年轻 makes sense by itself ("he seems young"), so adding 看来 doesn't make sense to me.

Question: Why is 看来 in the sentence 照他的年纪看来,他显得年轻？

I'm thinking it might be used to indicate some suspicion of his age, e.g., if a child was buying alcohol with a fake ID.  Or maybe I'm reading too much into this.
Although this sentence seems good to me, I think it can be better phrased as:

照他的年纪来看,他显得年轻。 

And 照 ... 来看 can be considered as a set phrase meaning “considering”
