This mechanistic variant is also known as the "ene-first" mechanism or the “ene-then-yne” mechanism. An "alkyne first" pathway would lead to a mixture of regioisomers, which can only be observed for a few substrates: NMR evidence favors the "ene-first" pathway, as new carbene proton resonances can be observed.
