This is exactly what I want, but my impression is that I get this:

Mk = \relative g' {
    \quoteDuring "Q" { s1*4*3/4 }
    \quoteDuring "Q" { s4*3 } }
    \quoteDuring "Q" { s4*3 }
}

It just ignores and removes the "\tag #'X {".

My intention is that Mk shall follow Mj, and when the \removewithtag #'X 
is active the Mb shall be excluded (the second time) in Mj as well as in 
Mk. In Mj this works very well, but Mk ignores the tag and continues 
with Mb after Mc.


===>

Addendum:
My thought was that when \removeWithTag #'X is active, the variables 
would be:
 Mj = { \Ma \Mb \Mc \Md }
 Mk = \relative g' {
  \quoteDuring "Q" { s1*4*3/4 }
  \quoteDuring "Q" { s4*3 }
 }
 \addQuote "Q" { \Ma \Mb \Mc \Md }

so because Mj now does not contain the second \Mb, the quote in Mk 
should copy \Md, but as far as I can see \Mk does not behave so.
