Minkowski used 'Zeitachse' (axis of time) and 'Weltlinie' (worldline). 
These are different concepts, even if they are related.

Minkowski discusses the features of a four dimensional spacetime, which 
has to any axis of time three axis of space.

So there should be a multiple set of spaces and many possible axis of time.

This is, in short, what Minkowski wrote in 1908.

Einstein had a different concept about space (and Minkowski mentioned 
this explicitly).

https://en.wikisource.org/wiki/Space_and_Time_(Saha)

quote

"But to perceive clearly that the time of an electron is as good as the 
time of any other electron, i.e. t, i' are to be regarded as equivalent, 
has been the service of A. Einstein [Ann. d. Phys. 891, p. 1905, Jahrb. 
d. Radis... 4-4-1 1—1907] There the concept of time was shown to be 
completely and unambiguously established by natural phenomena. But the 
concept of space was not arrived at, either by Einstein or Lorentz, 
probably because in the case of the above-mentioned spatial 
transformations, where the (x', y') plane coincides with the x-t plane, 
the significance is possible that the x-axis of space some-how remains 
conserved in its position.

We can approach the idea of space in a corresponding manner, though some 
may regard the attempt as rather fantastical.

According to these ideas, the word "Relativity-Postulate" which has been 
coined for the demands of invariance in the group G, seems to be rather 
inexpressive for a true understanding of the group Gc, and for further 
progress. Because the sense of the postulate is that the 
four-dimensional world is given in space and time by phenomena only, but 
the projection in time and space can be handled with a certain freedom, 
and therefore I would rather like to give to this assertion the name 
"The Postulate of the Absolute world" [World-Postulate]. "


So Minkowski WROTE in his book, that Einstein had a different view.
