The problem is with all features implemented by external if-*.d scripts.
If e.g. a bridge is created by the first defined afi, the second script
will fail. And if it does not fail on up then everything will still
break on a down event, when the script run by the first AFI will destroy
the interface and ifupdown will be able to remove the IP address of the
second AFI.
Bugs were opened long ago, but there is no interest/manpower to fix
them (which is not surprising if you have ever looked at the ifupdown
