Generated source files build with some differences on fresh checkout

Starting from a clean checkout of current master with the submodules:

$ git show HEAD
commit f4073b2595335f46485a9c8f1197209434a02445 (HEAD -> master, origin/master, origin/HEAD)
Merge: 959e2dfe9 7a17ac1d0
Author: Jose Luis Martinez <jlmartinez@capside.com>
Date:   Fri Sep 28 09:52:27 2018 +0200
...

$ git submodule init
Submodule 'botocore' (https://github.com/pplu/botocore.git) registered for path 'botocore'

$ git submodule update
Submodule path 'botocore': checked out '8eb2d131748e6f8e240fb8da2ee6fb2c71143191'

$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

I rebuild the generated classes:

$ carton exec builder-bin/gen_classes.pl --paws_pm --classes
Processing botocore/botocore/data/acm/2015-12-08/service-2.json
Processing botocore/botocore/data/acm-pca/2017-08-22/service-2.json
Processing botocore/botocore/data/alexaforbusiness/2017-11-09/service-2.json
...

But the generated files aren't the same as the ones checked into source:

$ git status
On branch master
Your branch is up to date with 'origin/master'.

An example diff shows minor differences:

Not every file shows differences, most match perfectly, so I suspect the process is generally working fine. This suggests perhaps some relatively minor difference in versions used?
