Does sequence matter in case of pam_env.so and pam_tally2.so together?

Question

Very short question.

auth        required      pam_env.so
auth        required      pam_tally2.so deny=3 even_deny_root unlock_time=120

or

auth        required      pam_tally2.so deny=3 even_deny_root unlock_time=120
auth        required      pam_env.so

Does the sequence matter in this case? If it does then why?

Edit1

To make it clear - pam_tally2.so possibly does not user environment variables pam_env.so could filter out, so the answer to this question is probably "the sequence does not matter". The main question should rather be - if I wrote my own pam module, would I have environment changed if pam_env.so was listed before me?
