Sure the altitudes amend the Dutchess Four clearance itself, but not the
clearence's explicit lost-comm procedure. That would only be amended if
ATC
issued explicit lost-comm altitudes too.

But when ATC tells you "Maintain 3000, expect 4000 after 10," isn't
"expect
4000" explicitly for lost-comm? From the AIM:

Hm, yes, that's a good point. But then "maintain 3000" isn't for lost comm.
So I guess the most literal (but not the most sensible) interpretation would
be to climb to 5000' as per the explicit Dutchess Four lost-comm procedure,
then descend to 4000' as per the overriding "expect 4000 after 10". Or
something like that.
