The M6T0101 is a tool change call for a lathe not a mill.

All the way back to post no.#4
The tool numbering stratergy will have to be well controlled if you use multiple tools with the same tool number but different offset numbers.
I dont think I would do it that way, as it's an accident waiting to happen, and for me I'd not have to wait long :-)
Maybe better set up the auto tool length measuring macro - at the start of your job, put in the tools for that particular job, let the machine measure the TLO's and then run the job.
