Hmm... yes and no."He is so deep in his books he would forget to eat."
Does it mean?
"He is so absorbed in his studies that he tends to forget to eat."

The part in blue is implied by the "would".
Not necessarily. The speaker could just mention a general fact about someone else:Is it talking about what he is doing right now?
"Bob is so absorbed by his books that he would forget to eat."
