Whispersync link doesn't travel between accounts unless the accounts are linked via the family household option. You can loan either the ebook or the audiobook and then use the one you didn't loan during the loan period.

If you have a linked family household account, only one person can read/listen to that selection because the mark of where you are in the book will keep changing as you read.

It was pretty funny once when my brother and I turned out to be listening to the same book - couldn't figure out why it would be in a completely different place every time I would start it again.
