No, not necessarily.
Superficially, perhaps, but I think .. reflecting more deliberately .. that we'd have to consider why humans "weave" and whether sasquatch shares that need. It comes down to biological need. Are they warm enough and dry enough without it? Bergmann's rule, covered with hair, etc. Just because WE might benefit from the additional warmth, wind resistance, etc from weaving does not mean they have the same need.
Essentially we have an algebra problem of one equation and two unknowns ... not uniquely solvable, at least for now.
My view: we need to be cautious about jumping to premature conclusions. I observe that people, having invested ego in a conclusion, have trouble backing away even when new data pretty clearly shows that they were wrong. I prefer to avoid that trap.
If I had to guess, though ... we're looking at something that, because of better biological adaptation, lives in a more ape-like rather than stone age human-like, way, though it may match us for strategic thinking when such is required. The black and white / only this or only that thinking is befuddled when encountering something that is not merely ape but not fully human (considering both biology and genetics, and if you wish, tool use). They truly represent a shade of gray we struggle to get our heads around.
