Very strange, this question about vlan looks like discussion we had
yesterday (or the day before...) about interfaces (versus packet defragmentation)

"IP conntracking" is about IP, and [V]LAN doesnt matter at all at this protocol level.

Same thing if you have two interfaces, eth0 & eth1 : IP conntrack tuples dont
include interface name/index
