I guess what he/she meant was that it sounds like two syllables (i.e., Dai-ske) to the ear of an English speaker. From a pedantic linguistic point of view, it actually contains four morae: Dá-í-s(ú)-ké. To analyze it as having two syllables violates several Japanese phonological rules (e.g., the absence of diphthongs in Japanese, prohibition of a consonant cluster, etc.). The "two-syllable" explanation, nonetheless, is good enough for non-academic purposes (e.g., for an English speaker who just wants to imitate its native pronunciation).

When you say it really fast, it sounds almost like "Dai-ske", but there are still very subtle differences between "Dai-ske" and "Da-i-s-ke" (mainly in the length of /i/ and /s/).
