this seems to differ from the JS version, but it's not a new difference https://github.com/mapbox/mapbox-gl-js/pull/6375/files#diff-c3312919f069eefcab838ca0389b355aR108 – I think what's happening is you add the offset before oy is passed to the js addVertex function so they are in fact the same, but just flagging to making sure
