It depends entirely on how you flashed your custom ROMs. If you flashed them from TWRP or other custom recovery, you should be safe because your bootloader and partition table (these are what cannot be downgraded without bricking) are still on 4.4.3. TWRP only restores/flashes /system, /boot, and (sometimes) /data.
If you ever flashed a 4.4.4 ROM from fastboot (and flashed motoboot.img and gpt.bin) then you could potentially be in big trouble if you go back to 4.4.3. (even if it is successful, you might brick during the future OTA to 4.4.4).
Anyways, as long as you are absolutely sure you never flashed the 4.4.4 bootloader or partition table, you should be safe.
