Here is what the .SKIP documentation says:

;*****************************************
Note that .SKIP does not execute or evaluate the code it is skipping.
Rather, it arbitrarily alters the current program counter to the nth
physical statement following the current point. This has implications
that may not be obvious on initial consideration:
;*****************************************

I would say what you see is consistent with this
statement.

Cheers,

David
