In DocuSign, when the X and Y coordinates are set to 0 for a checkbox (or other tab) but still appear offset on the PDF, this offset is typically very small.

the support told:

Generally, it ranges from about 5 to 10 pixels from the top left corner of the PDF document, as DocuSign often applies slight margins for tab alignment and placement consistency. The exact offset can vary depending on the PDF’s internal structure, resolution, and any margin or alignment adjustments DocuSign applies to ensure the checkbox visually aligns with other fields.

the customer want have the option without offset when x/y set to 0.
