Is it possible that your using cutter comp & your lead in is not proper?
In your "distance to go" can you see the machine making the comp along the length of the 1st contour?
-
One benefit of having your post output the redundant "Y0." is that your turning tool paths will remain on the same plane if you use a backplotter like CIMCO. The same goes for "C0."
I often switch back & forth between Lathe & Mill backplot to view my toolpaths.

Below is an example of proper code for transforming a C-axis Contour toolpath. (no Y-axis).
The text in blue is what I had to add.
I have tried this with MPLFAN, & MPLMASTER, and i get the same results.
The posts I have tested are for Fanuc and Okuma Controls.
When I try to do this same thing using Y-axis, the output is perfect.

Below is what my post actually outputs. (no Y-axis).
The text in red is where the post seems to reset C-axis to zero each time.(from what i gather in the debugger).

If i were to chain all 4 holes and not use Transform, the code would be correct like below.
The problem is, I want my operator to be able to read the code, & this is much easier if the C-axis is rotated between each location and basically the same program is run again.
Also this is just an extrememly simple example to be able to read the code easier.

2 of my lathes here do not have Y-axis, and I do this type of operation almost daily.
I have searched through this forum and have not seen anyone make mention of this issue.
So I always thought that I was doing something wrong.
Anybody else come across this?

You can use reference points to create a clearance position.
Then you could set your clearance & retract points inside your pilot hole.
