Ok....bear with me.
Normally what you were told is true. If you had flashed the entire 4.4.3 Tmobile SBF, your bootloader and partition table (these are what you cannot downgrade) would be on 4.4.3, and downgrading would likely brick you.
However, since you used the flashable zip, and NOT the full SBF, your bootloader and partition table are still on 4.4.2. You see, the flashable zip ONLY updates /system and /boot -- it leaves the bootloader and partition table untouched.
As such, your bootloader and partition table are STILL on 4.4.2. This means that you are completely safe to flash the full 4.4.2 Indian XT1052 SBF (OR restore your TWRP backup), because your bootloader and partition table were never updated past 4.4.2. You can then subsequently take the OTA to 4.4.4 without fear of bricking.
Does this all make sense?
