I guess that, as part of the alignment, I would like to have seen the measurements that were made for toe, caster and camber, both front and rear, in order to match them up to Volvo specs.... but I'm not a particularly trusting kinda' guy. At least with that info I'd have an idea what the suspension's doing. I don't know whether the Volvo TSB pertaining to Camber Adjustment is applicable to the 1991 740T, but most of the 700 series cars can have the camber adjusted by drilling holes in the upper support plate. Castor is also adjustable, or at least used to be, by using a longer or shorter control arm strut. These aren't the kind of thing that the shop is likely to know, unless they are Volvo oriented, and even with that info, they probably wouldn't be eager to mess with the suspension to that degree.
