The friction disk is being applied to retard or accelerate what is essentially a compressor. The requirement in force to slow down an off-throttle engine is much less than to accelerate one.

To compound this, on a down shift, the clutch re-engagement is generally slower for your typical driver so the delta between where the revs are when the clutch is disengaged to where the revs are when the clutch is re-engaged is greater, aka: even more work.
TRUTH!
I will amend my comment:
"There is no more strain put on a clutch by downshifting properly for the conditions then there is up shifting properly for the conditions.


And my usual disclaimer of:
"My statements are for regular driving only. Track and 'cuz racecar methods will vary"
