query-expressions

Issue with documentation regarding join:

https://msdn.microsoft.com/visualfsharpdocs/conceptual/query-expressions-%5bfsharp%5d
but not on
https://github.com/Microsoft/visualfsharpdocs/blob/live/docs/conceptual/query-expressions-[fsharp].md

(?)

Note that the order of the keys around the = sign in a join expression is significant.

It seems to be impossible to swap them around, also mentioned in

Can the documentation be elaborated on in WHICH case this can actually be swapped?
