This special IPv6 requirement for 3GPP mobile broadband connections is described in Section 5.2 of RFC6459 (IPv6 in 3rd Generation Partnership Project (3GPP)). This RFC also indicates that an "old" IPv6 Unicast prefix should be timed out after a Level-2 connection failure, even if the Router Advertisement lifetime for the prefix is still active. However, Windows 8.1 does currently not support this RFC guidance.
