No. Copy as name is used if you want to alter the precomposed name manually. Usually, Copy as Name alone should not cause any harm if you don't modify the text afterwards. However, there are different ways to interpret the ISDCF name, there have been different versions of this formatting, and not all servers do it right.
As you can see, the ISDCF recommends that all fields should be present, and empty fields should be filled with 'NULL':
'There MUST be an entry in EVERY field. Some systems count the number of “_” (underscores) to parse the information (NOT RECOMMENDED – BUT it’s done). If you have a non-relevent field, fill it with the letters “NULL”.'

But I think I have never seen a single DCP/CPL that actually makes use of 'NULL'. It would make real world DCP names very unreadable.
Sometimes, e.g. I erase the Feature version number manually, or I erase the OV extension if I do not plan to issue a VF, delete other unnecessary stuff that would e.g. make:
LastJedi_TLR-1-2D_S_EN-XX_INT_51_2K_DI_20171013_DTB_IOP_OV
into
LastJedi_TLR_S_EN-XX_51_2K_DI_20171013_DTB_IOP
Actually, these ISDCF names were never meant to be interpreted automatically. They were only meant to help the human operator with some experience and intuition, so, they don't follow a very strict formatting. The servers do not actually care. They may display it for convenience. The only real impact on Doremis is the Content Type (FTR, TLR, etc.), as the Doremi arranges content by content type in the Cinelister editor so it's a bit easier to tell features from trailers, ads, etc. when building playlists.
