Where do you get the conclusion that 1h bw has shorter reach than 1h sword?

I think I have seen multiple people claiming that a 1h bw has a shorter range than a 1h sword. I'm not sure where they get it, but I always thought they had the same range.

So I decided to test it out on leps. For short, what I did was:

Equip a bw, stand next to a lep, attack a few times, cannot reach, move slowly till I can finally reach it.

And then I switched to a 1h sword, and there was no way I could reach the lep without moving closer.

My conclusion comes out to be 1h bw has a longer ranger than 1h sword o.O

Note:
bw I used: Pig illustrated.
sword I used: Red kanata

attack used: normal attack
supportive skill used: maxed mastery for both and booster.


Edit:
The longest reaching animation seems to be the slash from your right hand side to your left hand side, when facing right.(hope somebody understands this, too lazy to post a pic)
