Took me quite some time to reproduce. ;)

$newCategoryFine = 'c2ategories'; // you are fine
$newCategoryBroken = 'categories2'; // broken

This is due to the internal working of addToAllTCAtypes() and it's usage
of strpos() on testing of the existance of the fieldname.

IMHO this really seems to be a general problem/issue with
addToAllTCAtypes() that migth be worth fixing.

If you add a fieldname that fully matches any part of an existing
fieldname you are likely to run into problems.

you can't add any field with names like 'great', 'feature' or 'field'.

Fixing it by renaming the default categories field to
'default_categories' would be a quick and easy workaround that leaves us
with a "terrible" field name. I'd like to see it fixed in another way.
