Hi, all. In the following sentence, I cannot figure out why there is a 'for'.

Attention avoids this by allowing the RNN processing the input to pass along information about each word it sees, and then for the RNN generating the output to focus on words as they become relevant.

Should not it be " Attention avoids this by allowing (the RNN processing the input) to pass ..., and then (the RNN generating the output) to focus ..."

Sincerely.

@Flysnowing,

I disagree that 'for' is superfluous. It's this 'then'.
