That's an interesting thing, but there's no win-wins in capitalism. Rockpoint offered less than they'd otherwise lose, which by definition probably less than Millennium would otherwise gain.
The flipside to that is that a wider gap between buildings helps Millennium's clients as much as Rockpoint's.
For sure. I went looking for Rockpoint's comment letter on the project--happily it took only a few moments to track-down on the BPDA archived project subpage:

It's worth quoting at length, as [not surprisingly], the Rockpoint counsel goes into very precise detail re: the various ways they feel the final design proposal for the tower would be encroaching upon 101 Federal and consequently its tenants.
(I boldfaced some passages for emphasis. The portion of the Rockpoint comment letter I'm quoting from is pp. 29-30 of the PDF containing all the comment letters.)
"The revised massing of the Project gives us great pause and raises significant concerns for Rockpoint . . . The Federal Street elevation now extends straight up the face of the building, with a correspondingly bulkier massing, and
the resulting building design places the Project directly adjacent to the 75-101 Federal Street Building at a distance of only 22 feet on average and as close as 14 feet. By contrast, typical minimum building separation distances for high rise towers in Boston are closer to 40 feet (One Lincoln Street and 100 Summer Street) to 50 feet or more (125 + 145 High Street, One Federal Street and One Beacon Street). The design of the proposed project thus creates a "looming" effect not only on the 75-101 Federal Street building, but also on other buildings in the area such as the suite of historic buildings framing Winthrop Square, as well as Winthrop Square itself. This design is inconsistent with the City's own RFP for the Winthrop Square garage site, which called for the building's massing to "enhance the composition of the surrounding buildings" and to provide "appropriate setbacks."
We ask that the proponent be required to revise the project design to create more setbacks from adjacent buildings and reduce the massing on the Federal Street frontage. We enclose a massing analysis which illustrates the massing incongruities of the Project in relation to existing tall buildings in Boston. "
"As outlined in the draft Development Plan for the Planned Development Area that is proposed to be created at the Garage parcel, the project will have a 34.5 maximum Floor Area Ratio (FAR). This FAR is substantially (i.e., more than 25%) in excess of the FAR approved for other tall Boston office buildings, such as the One Financial Center tower, with an FAR of about 27, or the 53 State Street/Exchange Place tower, with an FAR of about 28. Furthermore, the Project will be a mid-block, "infill" building, whereas buildings of this scale in Boston are more typically located on a full City block (such as the 200 Clarendon Street and the Federal Reserve buildings) or on corner lots (such as the 28 State Street, 60 State Street and 100 Summer Street buildings). The project site's mid-block location demands an especially sensitive massing solution which sadly, is not represented in the Project's current design. As noted above, we ask that the proponent be required to revise the Project design to create a massing that is more sensitive to its setting. We note that the comments we are raising in this letter with respect to massing and density mirror those raised by numerous Boston Civic Design Commissioners at the February 6, 2018 BCDC public hearing on the Project."
