Rule G36 question: Paddles

[gontholianguy]

I am wondering about a certain part of rule G36. The manual states that "Any extension above 60 in. may not exceed a 6 in. diameter vertical cylinder", but I was wondering if a "paddle" type blocker that, in the process of swinging upward, would exceed the bounds of the 6 in cylinder, but when in position would fit within the cylinder. I made a simple diagram to help explain what I'm talking about.

Presumably, it would be allowed, but I'm not taking any chances!
