Doubt in Tools/Widl/register.c

I have the following doubt:
put_str( indent, "'%s' = s '%s'\n", vi_progid, descr );
put_str( indent++, "

{\n" ); put_str( indent, "CLSID = s '%s'\n", format_uuid( uuid ) ); if (progid && strcmp( progid, vi_progid )) put_str( indent, "CurVer = s '%s'\n", progid ); put_str( --indent, "}

\n" );

Shouldnt it be:
+ if (progid && !strcmp( progid, vi_progid )) put_str( indent, "CurVer = s '%s'\n", progid );
?
