depending of the line length. Is It OK?

Yes, a 1/8WL line is a *SPECIAL CASE* where zero interference exists.
In the power density equation:

Ptot = P1 + P2 + 2*SQRT(P1*P2)*cos(A)

if A = 90, then cos(A) = 0 and there is no interference term and no
interference. When you go to a 1/4WL line, it is no longer a special
case where cos(A)=0 and I have not published anything on my web page
about that condition.
