On a 3 axis machine with a rotary/tilting rotary table added then TLO would just work as intended with or without the table on the machine. On a machine that tilts the cutting tool then the TLO would have to be calculated for every tool position. This is a very simple calculation. With multiaxis TLO, you are able to use GCode programs no matter if a tool length is used to generate the code or not. You can compensate for pivot distance and/or tool length by modifying the value in the TLO register in the control. This complicates the use of TLO by adding human input in the register, but with operator attention it works very well.
