Did a city councilor who agreed not to get involved in BC issues get involved in BC issues?

Mayoral candidate Kevin McCrea posts a copy of a letter that would seem to indicate Allston/Brighton City Councilor Mark Ciommo managed to convince at-large Councilor (and mayoral candidate) Sam Yoon to "scale back" a proposed hearing order on Boston College's expansion plans. Ciommo had promised to recuse himself from BC deliberations because his son got a scholarship there.

Harry Mattison posts Ciommo's reply:

... I have not contradicted any aspects of my disclosure form.

Councilor Yoon approached me to co-sponsor a late-file Order for a Hearing regarding the BRA process with Boston College's [institutional master plan]. I provided him with my feedback that I supported several components of the Order for a Hearing, but that I thought that some of the language was inaccurate. I also felt that some of the language was politically charged.

My intent was to remove politics from the discussion and focus on the BRA process. I think the end result was a more productive hearing. ...
