It won't hurt to search the archives for the differences between
OS-level memory reporting tools, like top and the windows task manager,
and executable-level tools (the JVM in this case). This has been
discussed and explained many times in the past.
There's no conflict as the two are not expected to agree. The top
command includes overhead space far beyond the heap. Your GC snapshot
sent to the list earlier is just that: the portion of the heap currently
handled by the garbage collector. The heap could've grown right after
the snapshot you sent to the list. There are also parts of the JVM
taking memory not shown on the verbose:gc output, and then there's the
OS-level memory consumption beyond the JVM itself.
