How the prefixes configured on point-to-point link are handled in OSPFv3

What does the following sentence (section 3.4.3.7) in the RFC 2740 mean?

Router RTX examines its list of interfaces to the area. If the

interface is in state Down, its prefixes are not included. If the

interface has been reported in RTX's router-LSA as a Type 2 link

description (link to transit network), its prefixes are not

included (they will be included in the intra-area-prefix-LSA for

the link instead). If the interface type is Point-to-MultiPoint,

or the interface is in state Loopback, or the interface connects

to a point-to-point link which has not been assigned a prefix,

then the site-local and global scope IPv6 addresses associated

with the interface (if any) are copied into the intra-area-

prefix-LSA, setting the LA-bit in the PrefixOptions field, and

setting the PrefixLength to 128 and the Metric to 0. Otherwise,

the list of site-local and global prefixes configured in RTX for

the link are copied into the intra-area-prefix-LSA by specifying

the PrefixLength, PrefixOptions, and Address Prefix fields. The

Metric field for each of these prefixes is set to the interface's

output cost.

Considering the following example

RTA<serial 1>-------------------<serial1>RTB

Does it mean that RTA will advertise the prefix configured on serial 1 with LA bit set, iff there is no prefix configured on the serial1 of RTB?
