Unexpected multiplication in output

Hey Guys.

I'm trying to make rotation of series of breps in Python. Everything works more or less,

but output geometry always multiplies, i can not figure out why. Maybe it has something

to do with output methods (ghdoc.Objects.Geometries or List)? But anyway i have

multiplied result even if input is one brep, without any functions at all.

I'm shure it is something evident, but as it my first steps with Python i ask for

help. Files attached.

Thanks in advance.
