We could say instead:
"The CPE router will convert the packet from one L2 domain to another
(e.g. through MAC rewrite) when the packet crosses L2 domains (e.g. from
WAN to LAN or LAN to WAN)".

Is 'rewriting' actually a valid description of what's happening?
Suppose one of those interfaces has no MAC?
