ServiceX auto_schema and similar column names

[alexander-held]

Describe the bug
I have not understood this fully. I have a setup where I compare a calculation with a pure coffea processor to a ServiceX processor, which receives data through a func_adl query. I am cutting on jet.pt. When a column with name jet_pt_uncorr is fed into the processor in addition, it seems to interfere with the jet.pt cut. I am not sure what ends up happening to that column, it is neither events.jet.pt_uncorr nor events.jet.pt.uncorr in the processor.

To Reproduce
See https://gist.github.com/alexander-held/7a3f3e001bca54342bfa93040bdf428a.

By default, feeding all columns to the processor:

after filter 35905

When commenting out jet_pt_uncorr": e.jet_pt_uncorr (which is not used in the processor):

after filter 36673

With USE_SERVICEX = False at the top (no ServiceX used):

after filter 36673

Expected behavior
I have not manually verified the expected count, but suspect that 36673 is correct. I see the potential ambiguity of interpreting the _ in pt_uncorr, but would expect the presence of this column to not interfere with jet.pt.

Output
see above
