That is something totaly different. it serves as a tweak to load Winpe faster, but does not apply to actual TS deployments inside winpe. But the link you provided is something that all users of SCCM should actualy change to get winpe loading faster. It's a matter of seconds instead of minutes to load winpe when this value is set to at least 8192. 16384 does not work on all devices but the very newest computers.
