They’re two shadows, but nothing calls them point sources;
I claim that any reasonable implementer would from such descriptions absolutely presume them to be distant (as in, never have it even occur to them it might be otherwise).
The only detail that seems confusing and could support otherwise is the sentence “On the web, shadows are depicted by manipulating the y-axis only.”
(I’m using roughly SVG’s terminology: fePointLight has x, y and z, which can be approximately infinitely far away but it’ll only be approximately so, and feDistantLight, which has azimuth and elevation, and projects from infinity.)
