I think they will have less chance of being stuck, but can't say for sure cause I haven't tested it for extreme cases. I never saw them stucked so far. The whole point of building two consecutive tank trap in different direction is to remove the gap between them. So yes, I guess it would minimize the chacne of RE getting stuck between them.
R.E will struck between 2 tank trap if:
1/ they build the first one and turn left/right to build another > stuck. More often when you build 2 tank trap on VP.
2/ when you give them too many order "click" they will build a tank trap, stick together on 1 spot, turn left or right and build second tank trap > stuck. Just like sometime I click them to cap but 3/4 model stay in random cover and let 1 guy go.
