Unexpected option "genome-aligner" in the console UGENE

The issue was detected on a Windows NSIS x64 snapshot (rev. 4161).
I launched command-line version of UGENE with "-help" option. There was an option "-genome-aligner" with description "UGENE Short Reads Aligner" (see the attached screenshot). The option (if it is an option), differs very much from other options and it's meaning is not clear.
