That's not the reason.
It's a common misunderstanding:

Looping is done by the phase argument,
the loop argument enables wrapping of buffer indices.
This is badly explained in the helpfile,
actually the argname is also misleading.

(
s = Server.local;
b = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav");
)

b.numFrames

-> 188893

// no wrapping, so pause with index values above numFrames, but still looping because of LFSaw

{ BufRd.ar(1, b, LFSaw.ar(BufDur.ir(b).reciprocal / 2, 1).range(0, BufFrames.ir(b) * 2).poll, 0) }.play;

// wrapping, so no pause with index values above numFrames, looping because of LFSaw

{ BufRd.ar(1, b, LFSaw.ar(BufDur.ir(b).reciprocal / 2, 1).range(0, BufFrames.ir(b) * 2).poll, 1) }.play;
