I agree with Gary in that it seems perfectly reasonable that KE and NTP
could be on different address families. If an IPv4 KE server returns a
hostname with only AAAA records, that would happen. Or if it returns an
IPv6 address directly. Or vice versa, with an IPv6 KE server returning a
hostname with only A records or returning an IPv4 address directly.

However, based on the current documentation, I wouldn't expect "server
-4 HOSTNAME -6" to be valid syntax. If this is supposed to work, the
documentation should be updated. And even then, I'd expect that the -4
or -6 should be part of and thus after "nts", not before it. Or perhaps
the -4 or -6 should be part of "ask" or "require", to make it clear that
it applies to the NTP server?

I would, though, expect this sort of syntax to work, once ask and
require are implemented:
server -4 HOSTNAME ask 2001:DB8::1
server -4 HOSTNAME require 2001:DB8::1
server -6 HOSTNAME ask 1.2.3.4
server -6 HOSTNAME require 1.2.3.4
