I think at the end of the day I just disagree with some of the design decisions (link via ukelele on davis_square): not only are they explicit about "strongly [preferring] routing onto these trails rather than roads open to automobile traffic", they also favor flatter routes, less busy roads, and fewer intersections. 225 does in fact get noticeably hilly west of Carlisle Center, and there's a couple of significant hills on 4, which does sort of account for those particular routings, though at the cost of being on much busier 2A and 110.
