I don't think it needs to, it will either do the next G0 (which is no
problem at all) or do a G1 which might get a bit boring. (and will
start from the wrong place). I think that if you are inserting a
manual tool change in your code then you know you will be touching off
after it, and would know to put in a G0.It is conceptually no
different from a tool change at a safe position. (but you have to
trust the operator to hand control back at a safe position)
