You shouldn't be be able to re-cast a bound equipment spell
In the original game, if you cast a bound equipment spell and try to cast again while it is still active, after the casting animation plays you will get the message "You cannot re-cast this spell while it is still in effect." and the countdown for the bound equipment item will not be reset. The failing spell sound does not play. The spell cost is subtracted from your magicka.
In OpenMW you can re-cast the spell.
Tested on the latest OpenMW master (commit 6b45a757) on Windows 7, 64-bit.
