I'm not expert in english. So just wanna make sure. in this picture it said smt like "If trooper reach edge of vertical wall then it consider finish climb". If my trooper have MOV 4" and wall is 4" height exacly I can climb right? (or do I need to hand on vertical wall at 4" height)
Yes, per this thread: https://forum.corvusbelli.com/threads/snapping-to-walls-and-roofs-during-vertical-movement.38466/ Basically my takeaway from that thread was: don't think of Climb as a type of Move, where you measure the distance travelled by a point on the troop's base. Instead, think of it as a purely vertical movement. Measure the vertical distance only (4" in your example). Horizontal shifting to get onto or off the roof is free. NB this doesn't apply to Climb+, which measures distance like Move, not like Climb.
