No surprise here.  EMC will prohibit some conditions of this, when
cutter diameter compensation is on, and either two lines or a line
leading into or out of an arc will cut an inside corner on the part.
It will let you do this without diameter compensation, because it then
doesn't know the size of the tool.

No, the lines are precisely tangent to the arc, at one of the 90 degree
corners of the arc.
