They absolutely lean in. If you noticed in my photo there's a bandsaw blade clamped there. That's to give me a straight "level" line around the whole tub to cut for mini tubs. A lot of guys will cut following the seam and then when they make the filler pieces they have to do it in multiple sections because it ends up in a compound shape. Mine is just a dead straight strip and fits perfect.
You can see the "lean" here ... that sawblade is dead nuts vertical !!
