Correct, combined with aggregation this is what your ISP is supposed to
do. Filtering private ASNs should not be necessary if everyone
configured things the way they are supposed to, which is not the case.

BGP table version is 29198, local router ID is 209.233.126.65
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal
Origin codes: i - IGP, e - EGP, ? - incomplete

   Network          Next Hop            Metric LocPrf Weight Path
*  3FFE:82A0::/28   3FFE:B00:C18::8C
                                       0 10566 12337 15671 65526 7521 i

The bottom line is that you should _not_ announce AS 7521 to AS 15671.
Also, AS 15671 should strip the private AS from the ASPATH.
