Basically correct. The idea is to "Analyse once, encode many".

Many of the recent CLI functions added to x265 are there to suit the demands of professional broadcast/OTT content providers, who may wish to create multiple resolution and bitrate copies of any one source.

The practical consumer application of this particular "reuse" functionality would be very niche.
