The English original of the message "sf createtemplate infoboxformat" refers to the "Right-hand-side", which is likely the "Left-hand-side" in RTL wikis. I suggest to amend it accordingly.
Else, we could open a bug suggesting to make it conditional, i.e. adding a {{#LTR:yes|no}} and/or {{RTL:yes|no}} syntax to messages.
