Covenants: question on library rules

Holographical books (books scribed by the author and not by a scribe) are arcane connections to the author that last for a year. The arcane connection is severed if the authors opinion of the subject changes (such as studying the subject for a season).

What happens if another magus has made the arcane connection permanent in the meantime?
Will fixing the arcane connection make it immune to the severing or will the connection be severed?

It'd probally still be connected...which is why you'd use a perdo vim spell to reduce the duration of the connection (so it expires) before you let your book go
