Demanding means it requires more of you, not that failure to meet those demands has a worse outcome.

By definition, you are wrong.
It depends on what you mean by 'demanding'. Healers have to not only handle the same mechanics as DPS (and sometimes more), but they also have to know boss mechanics to anticipate tank busters, raid wide dps, etc. Therefore, fights in general are more demanding on healers -- and to a certain extent tanks.

If you are looking at it from a button mashing standpoint, then yeah -- having a few cures, a cleanse, and some buffs isn't that complicated. It's all of the extra things healers have to manage that makes it 'demanding'. That, and the margin for error is much smaller than with DPS. A good healer can make up for bad DPS; the reverse, however, is not true.
