Hi @max89,
Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.
Did you have the flooring installed recently?
It looks like you might have floating floors which often use Scotia Trim to cover gaps against walls while still allowing small movements of the flooring.
The way the scotia was installed is likely due to the step in the timber making it difficult to continue the scotia trim around the corner. There is no functional reason that the scotia needs to continue around the corner.
It looks like the timber has been undercut to allow for the flooring to slide underneath. If you were to use a sealant, the flooring would be chemically attached to the timber, which would restrict its ability to "float".
As it looks clean, I don't see any reason to change anything.
Let me tag some of our helpful members for their opinions, @Dave-1, @Noyade, @Nailbag.
Let me know if you have any further questions.
Jacob
