No, if that were supported it would be identical to the first part.
The RCPT ACL is invoked for each RCPT and local_parts matches the
address given in *this* RCPT only.
Keep track of the addresses, building up in an $acl_m_... variable; or
set a flag variable when the first such address is encountered and take
action when you see the second address, if the flag variable it set
true.
You can initialise state in the acl_smtp_connect ACL and just use the
$acl_m_... variables, which are yours to define and exist for the
lifetime of the message.
Alternatively, you can use $recipients but not in RCPT itself. Perhaps
we should revisit this, and let $recipients build up across RCPT calls.
To use this, you'd ideally use it in the acl_smtp_predata but you'd
probably then hit all the clients that don't actually deal with the DATA
command being rejected, so you might choose acl_smtp_data instead.
