No, and it wouldn't have any legal bearing if they did.
If you read the TOS, it says that the TOS cannot be modified (except certain ways). An email exchange asking for clarification is NOT one of those ways. So you would not be able to wave the email exchange around in court and say it "overrides" the written TOS.
It might make a difference if the TOS was ambiguous, however that is exactly why Legal would have the CS rep's guts for garters if they caught one trying to interpret TOS.
If you want TOS interpreted, talk to your own lawyer. Your lawyer will be able to explain plain meaning, can research case law to see how anything unclear has been affected by precedent, and can tell you which areas are truly ambiguous, and your chances of winning a favorable interpretation on that.
You can also send a suggestion to the company's Legal Dept. asking them to amend TOS to remove ambiguities, which they would tend to want to do.
If you wanted them to reverse on an intentional clause, that is a harder road, but it has happened.
Lastly, if a clause is ambiguous or you think it is illegal, as long as you "have a stake", you can sue them to ask a judge to "Quiet the question", i.e. rule on how the interpretation will be made. Realistically this will simply cause them to amend TOS to sidestep the issue.
