It is unclear if Jack is going to be a doctor because there is no information about who Jack is. A last name is required to fond information about him.
He was in the 18th century because his time vortex manipulater malfuntioned and sent him there so he had to wait until the 21st century to find the doctor again (so he was there then) The simple answer is that Jack never visited the parallel Earth so he never passed through the void. Only the Doctor, Rose and Mickey (and the TARDIS) passed through the void from this side. So the real question should be, why didn't the TARDIS get pulled into the void. --- to heavy :) But didn't he get back to earth between then coz' how come he is in Torchwood now when he hasn't seen the doctor in 5,000 years? This is a different person: Jack was actually born in the 51st century. he was born in Boeshane Peninsula
