Hahaha, I don't know how it was when you applied to college, but I know that everyone these days is heavily padding their transcripts and resumes, turning bullshit into gold. I would bet that at least 75% of the student executive positions in various clubs and organizations and whatnot do either nothing, or very little beyond token duties, yet they take on aggrandizing titles. At McGill, every student organization exec is made up of President, and about five Vice Presidents, haha. Students will volunteer for 30 days from mid-June to mid-July and write it up as two months of volunteer work, or they'll volunteer for an afternoon every three weeks for a year and write it up as a year's worth. Most of the extracurricular activities I undertook during my high school career were because my parents put them upon me and created external incentives for my participation. It had nothing to with ambition or initiative, it's just a strategy that most asian parents use because they know how to game the system.
I'm sure there are plenty of hard working and ambitious do gooders who really do care about their community and give back, and I know quite a few, but they get lost amongst the masses of inflated CVs. I don't think it's logistically viable for colleges to give each applicant the inspection they might deserve. I'm also sure there are some very good admissions officers out there, who x-ray through bullshit and work predictive wonders given that all they have is whats on paper, but I think most will just check marks, test scores, skim the PSE, and make a call.
