The ESCape sequences can't contain values below 20h, because they will be ignored or used as control characters. Is for that you have added 33 to the coordinate values.

You can know more reading this document about the Video Driver Specifications.

Here is an extract:

In the same document you have the list of direct calls, if you want to compare them with the ESCape sequences.

Uah! It is a weird but good reason. But is more weird that does not happen with the x coordinates, 0 is 0, nothing to add. Maybe the reason is the Y is passed before. Anyway, the related calls to exos in the z88dk had something not trusty, sometimes don't work as expected. I can rewrite everything I need bypassing them.

This calls to exos using escape sequences seem to be very slow.
