In short; yup.
In depth; it'll depend. Some of the early Truths (with EMac silhouette underneath, specifically and likely the Pre-Sweden runs) will fly similar to current EMac Truth. However, those early runs (around when they started stamping "Made in Sweden") started to become flippy; hence the evolution of two different molds.
They retooled the mold and made the EMac Truth, which is buzz like, maybe a hair more fade. And the old mold is just the truth (5/5/-1/1 numbers). I'm not certain if this is 100% true, but it is close. I'm skeptical also, because the early truths (before "EMac") we're generally flatter, and now, they are all domey.
And there's this:

Now I'm just plugging:
I have several truths. Two pre Sweden's (lost one last year though..), a few with the small silhouette and "made in Sweden", a handful of emacs, and a couple Truths. I've been throwing the mold a long time. Feels better in the hand than a buzz, IMO, and flies similar.
I've been trying to work out the older truth mold and just work in the emacs, but they all serve a purpose.
