Please help me make sure I understand this right! (VC vs MC-LAG)

Hi there

In the past, I always saw people do stacking to have 'redundant' uplinks on the stack and the downstream gear.

I believe MC-LAG is the way to do it with Juniper these days for the hypothetical setup below:

Combo fw/router (not redundant, identified already as SPOF) feeding 2 links to, say, 2 EX4650's. These EX4650's have MC-LAG going between them and each EX4650 has one link to, say, EX3400's downstream. This setup would provide EX3400 uplink redundancy all the way to the firewall, right?
