Is this zoo statement about tree branches (and apes) true?

What's the real reason apes evolved to move through trees using arms rather than legs and a tail; why do they swing rather than jump? Surely not because "a tree branch can hold more weight above than it than below it"
(as purported by a suspect sheet of "fun facts" at the zoo).

My brother's friend just got a job at the zoo. The quote above is from the page given to them of "fun facts" to share with visitors.
Strictly from a mechanics point of view, the statement doesn't make any sense to us (but perhaps there's something we're missing?). Is the statement incomplete, imprecise, or just plain wrong, and how so?
