What does the phrase らしいと言えばらしい mean?


I am reading a book where one character describes another's reading habits,
and the person she is talking to says 「らしいと言えばらしいな」. From context, he seems to
be saying that her reading habits are unsurprising given her personality, but
why not just say 「らしいな」? What does the 「らしいと言えば」 part add?




'AといえばA' means "(I would not spontaneously say so, but) if you are going to
say A, I am not strongly against it". 'AらしいといえばAらしい' means "(I would not
spontaneously say so, but) if you are going to say it is characteristic of A,
I am not strongly against it".
