[gdal-dev] Difference results from QGIS project on fly and gdalwarp for EPSG:4326 of Sentinel 2 UTM zone 32?

I always thought QGIS and gdalwarp should return same result for projecting
a 2D Sentinel 2 image (e.g: T32UQD_20200421T102021_TCI_60m.jp2) from UTM 32
to EPSG:4326.

What I did was:

   - Open the .jp2 in QGis 2.14.9 with 'Enable on the fly CRS

   Warp the .jp2 to geotiff by gdalwarp:

   gdalwarp T32UQD_20200421T102021_TCI_60m.jp2 -t_srs EPSG:4326

But the output results from them look different significantly (on the left
hand side with QGIS it looks rotated and on the right hand side with
gdalwarp it looks aligned).
