Historically, sendmail has done duplicate removal with aliases for many years, and since it has such dominance most MTAs have copied/emulated this behaviour.
IIRC it does this with aliasing but not with virtusertables, which is where this becomes a problem. eg rcpt to: bob(a)acme.com rcpt to: wilma(a)acme.com and in the virtusertable: @acme.com: popaccount(a)isp.com This will (from memory, its been a while since we ran sendmail on the main mail system here), put two copies of the email into popaccount(a)isp.com. So for companies who are POPing "acme.com" out of a single POP account, they get the requisite number of messages and by looking at the envelope recipients, they figured out where to deliver it to at their end. Doesn't work with aliases though because as you say, sendmail (and most other MTAs) will delete the duplicates. One solution is to force the mail to be split into seperate messages each with one recipient at some point.
