To answer myself, yes it is safe.

The question is why PlanetCNC is bothered by that Z there, if it is standard on Fanuc?

We don't need to reinvent the wheel.

This is not standard for Fanuc format; this has just been made by a postprocessor that someone has created.

Use Single Block and see if it does move the Z25. if it does then the G80 has not canceled the canned cycle until that line is complete which then it is ok for it to be there, it's not normal to be formatted like this but if it works then there is no problem with how it is formatted.
