Close. By declaring a vlan-Id in the BD definition -- the MX does vlan "normalisation" as JNPR calls it. (And does all the correct push/pop magic for you)
If you omit the vlan-id statement in the BD definition, then your statement is correct. Quick verify: show interfaces ge-2/1/5 will show input: push 0x8100.100 and output: pop. When the vlan-id is declared In the BD stanza.
