During offset mode, if G50 is commanded,the offset vector is temporarily
cancelled and thereafter offset mode is automatically restored.
In this case, without movement of offset cancel, the tool moves directly
from the intersecting point to the commanded point where offset vector
is canceled. Also when restored to offset mode, the tool moves directly
to the intersecting point.
