If you are close enough to smell patients it is a clinical experience but the description y ou posted does not use the word patients but requires the volunteer to be patient (not the same thing, obviously).
While this will help you become more comfortable dealing with elderly people, some of whom will have physical disabilities, psychiatric or neurological disorders affecting mood and/or memory, or be frail, they are living in a facility where they can be looked after in terms of housekeeping, meals, socialization with others, supervision of their medications and so forth. This isn't clinical any more than babysitting or substitute teaching is a clinical activity related to pediatrics. Sure, maybe it makes you more familiar with kids but the kids are patients.
This is a good volunteer experience but you should have some shadowing and some other paid or volunteer experience in a setting where you regularly see physicians or other health care providers at work.
