According to the book: UNIX Backup and recovery by Curtis Preston, on

Really confusing indeed. What I *think* it means is:
The (ufs|vx|*)restore program has an interface to extract single items
from a backup interface interactively, which gnutar lacks.
Amrecover brings a similar interface to backups made with gnutar.
But that interface is not intended to do full system restores:
e.g. many people are confused about the subtle difference between
"add *" and "add ." (actually me too, and when you have a broken disk,
and need restoring from tape, I usually don't have time to experiment).
Amrecover is intended to extract individual items from a tape, made
by any *dump program, but also by gnutar.
For full restores, you better use amrestore + pipe to appropriate
restore program.
Does this mean that I cannot use amrecover to restore a set of files
from a DLE that is being backed up with (ufs)dump ?
I don't use (ufs)dump anymore since more than 3 years now, but when
I tried it before, it was possible without any problem.
Beware that vendor restore tools are filesytem specific: you cannot
restore a ufsdump from solaris on a linux system.
In other words, does amanda indexing only work if you use gnu-tar ?
No, it works both for (ufs|vx|...)dump and gnutar.
