They should be unique, yes, but without the interface name unroutable. The
question is if it matters in this case.

I can only explain why you must use an interface name when connecting to
the other host over link-local address (which is BTW not recommended - why
do you, Juan Antonio, need it?):

Each interface has its own link-local address, but all of them fall into
fe80::/64 prefix. As there is a route to fe80::/64 on each interface you
must explicitly specify through which interface the packet should leave.
Otherwise the kernel would be confused.
