Would Susie allow BUTINES/BUTYNES?

According to Lexico and Premium:
The two alkynes are "1-butyne" or "but-1-yne" (CH≡CCH₂CH₃) and "2-butyne" or "but-2-yne" (CH₃C≡CCH₃C); both are gases at room temperature. The other two isomers are buta-1-3-diene (CH₂=CHCH=CH₂) and buta-1-2-diene (CH₂=C=CHCH₃). >>>These are no longer referred to as butynes.<<<

The "these are no longer referred to as butynes" is talking only about the latter two isomers. The former two are still called butynes and "butynes" is still a word
