pg_ctl start has to be launched from bin directory, path ignored (pg 10 beta 3). Normal?

as administrator command-line:
D:\PostgreSQL\10beta3>pg_env
D:\PostgreSQL\10beta3>pg_ctl stop
could not find a "pg_ctl" to execute
waiting for server to shut down.... done
server stopped

D:\PostgreSQL\10beta3>pg_ctl start
could not find a "pg_ctl" to execute
could not find a "pg_ctl" to execute
could not find a "pg_ctl" to execute
The program "postgres" is needed by pg_ctl but was not found in the
same directory as "pg_ctl".
Check your installation.

D:\PostgreSQL\10beta3>cd bin

D:\PostgreSQL\10beta3\bin>pg_ctl start
