That looks like badly written syntax, not a bug, at first sight.

Docs for ${run } :-

"If the option preexpand is not used, the command string is split into
individual arguments by spaces and then each argument is expanded."

Debug shows (just by adding "-d+all") :-

12:07:09.051 1210885 direct command:
12:07:09.051 1210885 argv[0] = '/usr/bin/false'
12:07:09.051 1210885 argv[1] = 'identity'
12:07:09.051 1210885 argv[2] = '${if'
12:07:09.051 1210885 argv[3] = 'def:sender_address_domain'
