I'd suggest re-reading what they're saying. The "just" is an acknowledgement that everyone does this. And, actually this was taken from a CroMo frame page, so nothing about carbon layup.
"Rather than limiting frame size variations to
just different length top, seat and head tubes lengths, we take an all-inclusive look at each frame’s total configuration. Every SSD frame will also feature size-specific BB drop, rear center, fork offset/trail and SST technology."
Here's a Spesh diverge Geo chart.. how many BB drop variations are there (Jamis has 5 different drops depending on frame size). Spesh also with only 2 different chainstay lengths, Jamis has 4. Also notice how the Diverge Trail just keeps dropping as you go up in frame size, vs making an attempt to keep the trail (bike handling/feel) in the same ballpark through the sizes.
