It does more or less convey that impression.

The problem, from the demangler perspective, is that the demangler
can't tell which vendor qualifiers are order-insensitive and which are
order-sensitive.  Thus any difference in behaviour between the two,
particularly in how they substitute, is a problem for the demangler.
