Origin of the plane constructed at an angle

[SirishaShashikanth]

I constructed a plane at an angle to the existing axis. When I tried to sketch something, I found that the origin is different from basic origin. May I know where it is actually taking the origin. When I sketched a line on this axis and again constructed a plane at an angle, the origin again shifted to something else. Can anyone please let me know where it assumes the origin in sketch?

I think it's a bug.  It happens to me as well.  For some reason, the center of the sketch grid does not line up with the component origin.
