Yeah it very well may be just bad luck overall but its still pretty interesting. Reminds me a bit of the western New York ordeal where you have several tornado tracks which are eerie similar...some where the start/end points are nearly identical.
But what you're saying about the warm season low tracks makes a ton of sense. Historically, we've seen plenty of these setups where due to the low track, we don't really drive the warm front northwards through New England, it tends to get hung up around the coast...so add the extra fuel to interact with that boundary and, viola.
