Yup, confirmed: the ROCA guys deliberately obfuscated their vulnerable key test (and made it slower). This is sad.https://github.com/crocs-muni/roca/issues/39 …

It took me 5 minutes to deobfuscate that stuff; now I have crypto nerd friends trying to guess their method anyway, which is the fun part ;)
OTOH, there is a performance impact of their obfuscation, and it can also lead to bugs being introduced. So it's not negative-free.
