Cut back clematis at front

Ladders adequate, if rather wobbly. I’d rather not rest the top of the ladder against the gutter. This shouldn’t be necessary in the future if I do this cutting back every year. It’s hard to tell which way the stems are growing, so there may be some orphaned stems.

Could this rather bare (of flowers) patch, just where I had the ladder, be due to this late cutting back? Get both clematis monata out of the eaves after they’ve flowered this year.
