irb -r yaml
irb(main):001:0> YAML.load("")
=> false

So the return value from load is in a and as there are no more values,
the rest of the variables (in this case xx) gets nil
Without * the results are the same:

irb -r yaml
irb(main):001:0> x,xx = nil
=> [nil]
irb(main):002:0> p x.class
NilClass
=> nil
irb(main):003:0> p xx.class
NilClass
=> nil
irb(main):004:0> x, xx= YAML.load("")
=> [false]
irb(main):005:0> p x.class
FalseClass
=> nil
irb(main):006:0> p xx.class
NilClass
=> nil
