They don't.

Emacs shows both the "Name" and the "Old Name" properties of
characters as completion candidates, while Python evidently supports
only "Name".  If you type "C-x 8 RET LESS TAB", then you will see
among the completion candidates both "LESS THAN WITH DOT" and
"LESS-THAN WITH DOT".  The former is the "old name" of this character,
according to the Unicode Character Database (which is where Emacs
obtains the names and other properties of characters).
