Maybe you're misreading the output. There are three separate objects
shown:
/usr/lib(64)?/libHermes\.so.*
regular file
system_u:object_r:textrel_shlib_t:s0
This one marks libHermes\.so.* under /usr/lib or /usr/lib64 as
textrel_shlib_t
/usr(/.*)?/Reader/intellinux/SPPlugins/ADMPlugin\.apl
regular file
system_u:object_r:textrel_shlib_t:s0
This one marks Reader/intellinux/SPPlugins/ADMPlugin.apl anywhere
under /usr as being textrel_shlib_t
/usr/local/.*\.so(\.[^/]*)*
regular file
system_u:object_r:shlib_t:s0
This one marks any .so* file under /usr/local as being shlib_t
Whilst the second and third potentially conflict, the second should
"win" for the file concerned because it's a more specific match.
