Those two attributes may be a consequence of forced password changes but
are not sufficient to advocate or not advocate such a strategey.

1 day after the breach your data had been compromised. Changing your
password 10 days later on in your 1 month cycle doesn't seem to me to
be reactive security. Better than nothing, I suppose, but closing the
door after etc.

In any case, your 20 character, high entropy password was your ultimate
defence. (Not unless Yahoo! didn't hash).

If I had so little confidence in the password hashing procedures at the
site I might do the same. My problem would then come down to predicting
when a likely breach would occur.
