Default will it update to android 4.4.4 ?

hello! i m new to rooting..
i bought moto e two months ago with 4.4.3 and update it later to 4.4.4 via OTA.

Now i want to root it. should i downgrade it first or root it with 4.4.4
all i want is a rooted moto e with android 4.4.4 and stock rom.

would i get it with this method?
Thanks in advance.
