So far, everything is correct.


  but once I deflag the on fly projection

No, please, DO NOT DEFINE PROJECTION!!! if you want to reproject the data.

Define Projection should only be used if the layer has a false 
projection. It changes the SRS information, but not the coordinates or 
their units.

If you want your data in UTM 32N metres, rightclick on the layer, Save 
As ... and choose a different file name and EPSG:32632 as CRS.
