This only works because you changed org-time-stamp-formats in one of the
few safe ways.

Org declares org-time-stamp-formats and Org code treats its value as a
constant making various kinds of unsafe assumptions that can break
things if the value of org-time-stamp-formats is changed. For example,
it is assumed that first/last characters are triangular brackets; it is
assumed that the output can be parsed using parse-time-string; it is
assumed that 1..11 substring in the format contains a full date; it is
assumed that the formatted output conforms to timestamp syntax; etc.
