 Next, the client SHOULD modify the ordered list to interleave
 protocols and address families. Whichever combination of protocol
 and address family is first in the list should be followed by an
-address of the other protocol type and same address family, and then
-an endpoint from the same protocol and other address family. For example,
+endpoint of the other protocol type and same address family, then an
+endpoint from the same protocol and other address family, and then an
+endpoint from the other protocol and other address family. For example,
 if the first address in the sorted list is a QUIC IPv6 address, then
 the first TCP IPv6 address should be moved up in the list to be second
-in the list, and then the first QUIC IPv4 address should be moved up
