Try this one, from the doc.
Since assault weapons are not a major contributor to US gun homicide and the existing stock of guns is large, an assault weapon ban is unlikely to have an impact on gun violence. If coupled with a gun buyback
and no exemptions then it could be effective
Sounds a bit mandatory to me, how would you interpret no exemptions?

The "no exemptions" refers to the exemptions in the 1995 AWB I mentioned earlier. Exemptions were made for existing assault weapons and large capacity magazines. You were still allowed to buy and sell them. "No exemptions" means you would not be able to buy and sell them. You could keep the ones you own, you just could not sell them.
Again, that is not confiscation.
Here is what the memo says before the part you quoted:
The 1994 ban on large capacity magazines had limited effectiveness because 1) Large capacity clips are a durable good 2) There were an estimated 25 million guns with large capacity magazines in 1995 3) The 1994 law exempted magazines manufactured before 1994 so that the importation of large capacity magazines manufactured overseas before 1994 continued through the ban 4) while the price of the clips increased dramatically (80% during the ban) they were not unaffordable. A 2004 study of the 1994 law found: “because the ban has not yet reduced the use of [large capacity magazines] in crime, we cannot clearly credit the ban with any of the nation’s recent drop in gun violence.” The 1994 ban essentially did little to affect the supply of large capacity magazines. In order to have an impact, large capacity magazine regulation needs to sharply curtail their availability to include restrictions on importation, manufacture, sale, and possession. An exemption for previously owned magazines would nearly eliminate any impact. The program would need to be coupled with an extensive buyback of existing large capacity magazines.
Any assault weapons ban will fail again if it exempts previously owned magazines and assault weapons.
So a buyback would be ineffective as well because an assault weapon owner could sell their assault weapon to the government and then just go out and buy another one.
Without an exemption, they would not be able to do so. Thus: "Since assault weapons are not a major contributor to US gun homicide
and the existing stock of guns is
large, an assault weapon ban is unlikely to have an impact on gun violence. If coupled with a gun buyback and no exemptions then it could be effective."
The DOJ is recommending NOT exempting existing assault weapons and magazine from resale. This, coupled with a buyback, would reduce the availability of assault weapons.
