No, that is not accurate.  An install tape (for V9 or later) is a bootable tape with a backup set on it.  Bootable tapes have DOS labels, but backupsets have ANSI labels.  The install tape is a hybrid, part DOS, part ANSI.  I'd have to dig in the machinery to find the details, but I definitely remember that it's a rather odd beast.

If you do an image copy of the TAP file to tape none of this matters.
