I think some would argue that he didn't know how the world was which was what got him killed in the first place. In any case, he would have still had access to Jon if Reed took him, it didn't matter where Jon was kept. In fact Jon would have been much safer if kept with Reed given the Crannogmen's elusiveness which was stated many times in the books.
That wouldn't make any sense to me. IF Meera and Jon were twins, why not then take Meera instead and let Reed take Jon? Given all we know of Ned's character surely he would have thought of how this would affect his wife, and a daughter would at least pose no threat to her own son in the succession of Winterfell.
To be honest the pics in the OP are a bit blurry and it's hard to tell anything definitive. When I saw it on TV, it didn't look like it was tipped. Irregardless he is a wide receiver, he gets paid big money to catch a ball...so when that ball is in the vicinity of his hands, he should catch it.
