"New Record Only" Relationship

I've been developing a solution for a couple weeks now after taking a hard look back at the philosophy of FMP. After some very constructive critism, reading, re-reading and testing I've made an almost functional multi-user database.

I have a question on an inconsistancy I've found in the FMP User books published by

FMP 7: Lane, Bowers, Love, Moyer

FMP 8: Lane, Bowers, Love

After reviewing the section "New Record Only" relationships in Working with Portals I've found a relationship problem that I can't see to figure out which is correct or if it doesn't matter if your working with FMP 8-8.5.

FMP 7 states (pg452)

primeID_neighborhood-----[foreignID_Temp

FMP 8 states (pg478)

_kp_neighborhood-----[__kf_neighborhood

The premise, if you don't have these examples, is to use this relationship to create a new record in the related portal without scripting while using field definitions to auto "clear" the temp field upon autoenter the __kf_neighborhood field.

As you can see from the above two examples, directly from the book, have different relationships. Is this because FMP 8 is different with this respect to FMP7? Whish is correct?).
