Vertical and Horizontal three dots icon button usage

Despite the Material Design has great guideline documentation, I'm confused about vertical/horizontal dots icon for a Web App since for mobile, the vertical solution is a stablished pattern.

I found a post that says that vertical dots are for secondary options menu but I see some examples that show that the horizontal can be also used for that.

I'm redesigning a table list that have option menus but some are linked with option pages. Is okey to use the horizontal dot icon also as link for a option page instead of vertical menu?
