This seems broadly sensible. Only counting experience after schooling ends won't work for everyone though. I was employed full time as a software developer before I went to university. And I had 5 years of non-commercial experience before that while I was still in high school that most people won't have. Presumably there's some wiggle room for managers to use their judgement on what counts as experience, so it probably works out.
