Hans changed part of the \setuplayout code in the last betas (there are more than you can see in the ctx suite).
When context checks the layout (happens with \starttext and when it starts a new page) it test for the following defined layouts:
• “<pagenumber>”
• “-<pagenumber>”
• “last” (is only used for the last page of the document)
• “first” (is only used for the first page of the document)
• “unknown”
• “current”
• “odd” and “even” (used for left and right pages)
All entries in this list are reserved names but you can also define your own layout but in this case
you have to enable it with \setuplayout[<name>].
One of the new features in MkIV is that layout parameters can be inherited, e.g. when
you define a layout with the name “one” {\definelayout[one][..,..=..,..]) and another one with
the name two (\definelayout[two][one][..,..=..,..]) this will take the values from one of there
are nothing set for a value from one and when there is also nothing set for one the global
values are used (\setuplayout[..,..=..,..]).
