Barrages are an abstraction and as E&C has said when Jervis was consulted his reply does indicate that the allocation rules are not used in this process.
Not just that, JJ also wrote this in 2003 on the SG site, whilst Epic was in its playtest stages:
Jervis Johnson wrote:
I've changed the rules for barrage templates so that you roll to hit what's under the template, rather than just using the number of units under the template to determine the number of to hit dice rolled (which I the way it was before). The new method is slightly slower, but is much more intuitive.
Which clearly indicates how the actual allocation part of the rules are supposed to work, with a change away from the "standard front-to-back" allocation method as was used in early playtesting, to the latter-day "roll against units on an individual basis" method.
Jervis' reply to Neal 7 years later just reinforces what's already out there online (And in the wording of the rules themselves, for that matter).
