I'll assume that it also fixes entries with pipes or ; in a similar way. I think you'll find that most other commands work this way such as "yum - -y update --exclude=<something> gtk2 --enablerepo=<whatever>" will work no matter what order you put the switches or command arguments. That same email suggested that the behavior is due to change due to posix. I'm not sure what posix has to do with this, but apparently eventually you will need to use the command line in the form of <cmd> <switches> <arguments>. This is o.k. with me as it is the way I've always done it.
