Yes, probably a bug, but it is questionable if it is serious.
I.E worth doing a new maskset to fix this bug.

The bug only affect those that step up from the 4414, and
those that assume that registers have a known value at reset.

It is generally a good practice to avoid relying on reset values.

It is an unknown harmless condition on reset and takes two instructions to
fix after
reset. The problem is if you do not know about it.
