AliasSeq different from just using the symbol name(s)?

I understand that it won't be possible to pinpoint the cause 
without a reduced test case, but :

```D
int[] a,b,c,d,e;
void templatef(args...){/*...*/}
//...
auto seq = AliasSeq!(b,c,d);
templatef!(a,seq,e);
templatef!(a,b,c,d,e); //am i being mistaken for thinking these 
two template calls should be equivalent in behavior?
```
And if not, does it mean that the problem i encountered is a 
possible bug?
