It might relate to the need to exec another Java process just like the 
original. Some tests use particular techniques to find the Java under 
test and that might (just speculating) require knowing for certain 
whether it was 32-bit or 64-bit, otherwise they would also need to know 
whether to pass -d64 or not.

Examining the tests should make this more clear.
