Level: robocopy vs eacopy

``` console
C:\SOURCE
└── MEH

robocopy C:\SOURCE D:\BACKUP\SOURCE /e /xf * /lev:1

D:\BACKUP
└── SOURCE
```
but
``` console
eacopy C:\SOURCE D:\BACKUP\SOURCE /e /xf * /lev:1

D:\BACKUP       
└── SOURCE   
    └── MEH
```
Why `eacopy` does not respect `lev` switch here?
