My guess that PublicHealth is using the term "least osteopathic" more in terms of residency placement. The majority of NYCOMers tend to specialize but the same has occurred in nearly every DO school. This is likely due to financial debt incurred from tuition, geographic, and other personal factors that have nothing to do with NYCOM. However, we have many excellent faculty members at NYCOM (e.g. John & Capobianco who are also UNECOM alumni) who are devoted to osteopathic principles and philosophy. It is really up to you whether you want incorporate OPP.
Saying least osteopathic does still leave me confused by what you mean. 19 of us did match into PM&R this year. This is a field whose philosophy correlates well with osteopathy. If you compare where NYCOM students are going compared to other schools like UNECOM, you will see that we are not too different in terms of what fields we match into. I know that schools like PCSOM and UNECOM push hard to get their students to go into primary care but, nowadays, less students are motivated to go into primary care. The focus on primary care still doesn't equate being osteopathic.
As a side note, NYCOM has won UAAO chapter of the year for several years. Medical school is make you make of it.
