Yes, key servers are purely cumulative.
Information cannot be deleted or made to disappear from them,
including revoked or expired (sub)keys.
This is by design, so that noone can e.g. remove someone else's
(sub)key(s), signatures, preferences etc. from the key server network.

I don't know that service, but if that is the case, then I suggest you
take it up with the people who run the encrypt.to service. If it
cannot handle expired subkeys then they don't implement the OpenPGP
standard correctly.
