Confirming this too after wandering around Belgrade today. The local derived examples don't the bowl well below the x-height, and either the bar of the tee level with the x-height or fractionally above (presumably for balance).
My understanding (although the character/ligature has evolved) is that it's still a "hooked"/"bowled" tee, rather than (anything at all) to do with a Latin 'h' root.
