That is the intended behavior. See
https://wiki.asterisk.org/wiki/display/AST/Pattern+Matching#PatternMatching-MatchingonCallerID.
When you change the Caller ID and you are extension pattern matching on
that, the extension immediately changes. Thus, you will advance to the
next priority, but in a different extension. You never hit
goto(${CONTEXT},${EXTEN},1) because as soon as you change the Caller
ID, it's not going to pattern match on that priority anymore. It's going
to fall back to the more general extension match, with the next priority.
A simple way to avoid this might be rewriting using a separate context:
[rewrite-421]
exten => _X!,1,NoOp(cut +421 from CALLER)
same => n,Set(CALLERID(num)=${CALLERID(num):4})
same => n,Goto(incoming,${EXTEN},1)
[incoming]
exten => _X./_+421X,1,Goto(rewrite-421,${EXTEN},1)
exten => _X.,1,noop(main block)
exten => _X.,n,noop(main block #2)
exten => _X.,n,Set(GWNAME=out)
