I'm pretty sure the ICD2 DOES the bulk erase if code protect is on. Even
if it doesn't, you can't blame it for you trying to do something out of
spec.

It has nothing to do with the ICD2. The chip enforces this rule: if code
protect is on, a bulk erase is required before any programming takes.

If you don't supply the chip enough voltage to do the bulk erase, it
won't happen.
